now i don't have any archive file. is there any chance to recover the database ?If no archive log files are available you can't recover the datafile.You need to have all the archives from the time of offline backup was taken till the system datafile is lost.

    Library recovery: how can I recover a library after I get this message: "There was an error opening the database for the library “/Users/Jim/Pictures/Libraries/K2 Library.aplibrary”???

    Thanks a lot, Frank. The lsregister did the trick! I am testing this on 10.8.2.
    http://support.apple.com/kb/TA24770 : I deleted the "com.apple.LaunchServices.plist", and restarted the Finder, even logged off and on again; did not change anything. The file has not been recreated, so it may not be used anymore.

    The direct "copy and paste" from the post did not work: I had to retype it :
    /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSe rvices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
    but then it worked like a charm!
    Cheers

    And btw: I turned on the "-v" option for the lsregister to see, what was going on, and saw plenty of error messages (error -10811); so I repeated the command with "sudo". After that I still saw five iPhotos. Repeating as regular user finally got rid of the redundant iPhoto entries. It looks like registering as super user may be causing this trouble.

  • How can i recover my voicemails after updating my iPhone?

    How can i recover my voicemails after updating my iPhone?

    When one restores an iPhone from its own backup, visual voicemail is also restored. However, when one restores a new iPhone from a backup from a previous phone, the voicemails fail to restore. This occurred between my 3G to 4s, and again from the 4s to a 5s. Restoring the 4s once from its own backup resulted in voicemail recovery.
    My only explanation is that when a different SIM card is used, voicemails cannot restore as one would otherwise expect. Perhaps voicemails are inexplicably tied to their SIMs. Unfortunately, newer models of iPhones tend to use exceedingly different sizes, rendering one possible fix unpursuable. iBackupBot is the other possible solution: you can extract the voicemails from the backup and restore them onto the new iPhone individually.

    You can't unlock it without losing data. It's too late for that now. You totally erase the iPad when you unlock it and you will have to start all over again. Most of your purchased content can be downloaded again.

  • How can I re-install firefox without losing my data. It is Infested with ADS BY bame.

    Firefox is infested with "Ads by name".
    How can I get rid of it or how can I
    Re-Install firefox without losing any data?

    Couple other suggestions:
    Open the Windows '''Control Panel''', Add/Remove Programs. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help surface innocent sounding bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.
    Also, could you check whether Firefox has a non-standard '''connection setting'''? You can do that here:
    "3-bar" menu button (or Tools menu) > Options > Advanced > Network mini-tab > "Settings" button
    The default "Use system proxy settings" should piggyback on your Windows/IE "LAN" settings. But you can try "No proxy" to see whether that makes any difference.
    Finally, our support article [[Troubleshoot Firefox issues caused by malware]] lists '''cleaning tools''' other Firefox users have found useful. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
    Success?

  • How can you delete an app without losing saved data/progress?

    How can you delete an app without losing saved data/progress? Is there a way through iCloud? I have an 8gb 4th gen iPod touch. I have a lot of music, so with 8gb, space is limited. Some apps I have take up 20-30 MB. Some of these games I don't play that much, but I don't delete them because I have made a lot of progress (levels, scores, acheivements). It would be nice to delete some of these 30 MB apps that take up precious space, and them redownload them in the future when I have more space, but without having to start the whole game over.
    Also, I read somewhere that there might be a way to do this with iCloud, but I don't really know how.
    Thanks!

    This is the only way I know of.  It is messy though.

  • How can I recover a book I started from a file?

    I have recently installed the iPhoto 9.2.1 from App Store.
    I am having many problems with iPhoto after an electrical cut when I was working with it.
    First, when I opened iPhoto immediately after that, many of the events appeared in black box, when I open a file of these,  black boxes appears, photos could not being seeing, but click in one, the photo appears.
    I realized that those files I did not working with them for long.
    I am interested to recover them, How could I do it?
    I copy iPhoto Library into a external hard disc to safe and start from the beginning. I need to work in one book.
    Second,The photos for that book were in the external hard disc. I imported them into iPhoto and start working. I thought that everything was solved out.
    This morning when I opened the computer and iPhoto, My work, begun the previous day, was not there, iPhoto ask me if I want to recover iPhoto Library and  thinking that that was my last work, I said yes.
    But it was not, It was the old library, but the work that interests me has disappeared.
    How can I recover this work I started? It must be in some place.
    Thanks for your advice

    Sorry, it'll be impossible for any of us (the forum regulars) to post in this thread without making obvious suggestions like this; it's safe to ignore these suggestions, I understand that you are powerless here to make reasonable suggestions like "Fire the incompetent translation firm that can't keep up with its clients and retain one that actually has the licenses for the apps necessary to complete the project."  If nothing else, all of the people who search Google for the phrase "translation downsave CS5 CS4 book" will learn that the best answer is "tell your translation supplier that they will lose your business if they fail to upgrade."
    But in your case - no, I know of no such script to re-save a CS4 book from IDMLs spat out of CS5. The scripting forum is thataway; maybe they know of a script someone else has already written for this purpose. Mostly because, especically in a book file, one of the steps before saving the INDDs and book in CS4 should be "a human compares the IDML opened in CS4 against the INDDs in CS5, or PDFs generated from same, before Saving As CS4 INDD."

  • How can I recover Itunes songs after I changed my computer

    I have my lists of songs, songs, etc in my IPAD and IPOD. I changed the computer and as I downloaded ITUNES, it's empty. How can I transfer my songs and lists from my IPAD or IPOD to ITUNES?
    Thanks

    Of course it is empty... what did you seriously expect?
    Installing iTunes has never caused media to magically appear on a computer.
    The media is only where the user puts it.
    Copy the ENTIRE iTunes folder from the old computer or the backup of the old computer to the new computer.

  • How can I recover my game after I restored my iPad? The game was online so I thought it won't be affected even if I restore my ipad. After restoring, and downloading my game, it started to level 1. Please help. I've been playing that game for about a year

    My game was 'fashion story' and currently level 90. But after I restored my iPad, it went back to level 1. Please please help

    Do you have a backup of the device before you restored it? If you have a backup, try to restore the device from that backup.
    If you don't, I doubt that there's anything anyone here can do for you. Seems as though your save game, (despite being an "online" game) was wiped out with the restore. I'd say the vast majority of online games still do keep your save data on the device and NOT in "the cloud".
    In this case, a backup of the device would have helped you out...it's always wise to backup your device before proceeding with a restore, especially if you plan to restore the device as new.

  • How can I upgrade to ios5 without losing games data

    I need to upgrade my iPad, but if I do I will lose my game's data, and will need start all from the begining again. The backup made by iTunes do not save this kind of data. What can I do??????????

    Actually the backup that is created by iTunes IS where the game save data is supposed to be stored. The backup contains app data, app settings and in-app purchases. From what I understand - Many games are saved in the cloud on the game's servers as well, so depending upon the game, the backup doesn't come into play anyway.
    But the only way that you can ensure that the data will be saved is to backup the iPad.
