Apple tv gives me a message "cannot load "when playing music from my computer

When playing music on my apple tv from my computer library, in the last week or two I have received on a frequent basis a message that says "cannot load data". Any ideas what may be causing this ?

No, none that I am aware of.

When playing music from Ipod in my car, music suddenly stops and message appears to restore in iTunes. After a few minutes, it starts to play again. I hear a click and the apple logo shows on the screen. Any ideas??

You may need to do a Restore in iTunes.
Clicking sounds from an iPod that has a hard drive is probably not a good thing. It is possible that your iPod's hard drive is becoming unreliable.

I just installed the latest Apple TV software update today. I can still play music from my iPhone 4 to th eATV but purchased movies don't seem to start playing now - or else the buffering time is huge compared with the previous software version. Any fix

I installed the latest software update on our Apple TV - this allows us to access VIMEO. However, although we can still play music from an iPhone 4 we can no longer play purchased tv shows - unless the buffering process has been extended to be glacially slow! It just shows it is loading but under the previous software release a show would start in a minute or two, nothing is happening afer 4 or 5 minutes with this one.

Thank you BDAua. This is what I typed and the reply from Terminal
java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-11M4406)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01-451, mixed mode)
BTW - this application does NOT show up in the Applications folder and I consider that a bit odd.
I also tried typing Java for my computer to search for and this is what I got under

I cannot select or play music from Ipod touch

I am unable to select music at all directly from the ipod touch. I can access it thru my car stereo though. What all of a sudden happened?

I am replying to myself...I tried the reboot trick (home key & ON/Off button at the same time) and it did unfreeze !!! I can access my music again. Thanks to the other apple heads for their help!

TS1702 What does error message 8003 mean when downloading music from the iStore

Purchased an album from iTunes store and can see it has been downloaded but is 'greyed out', and will not play or sync with iPod. When looking further I see the majority oif the album's songs have an error message 8003 alongside them. Any clues as to the problem and a solution would be appreciated

In this context, the 8003 suggests the files are damaged.
If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copies of the tracks and try redownloading fresh copies.
Otherwise, I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the items that are not playing properly. If you can't see "Report a Problem" next to the items, click the "Report a problem" button. Now click the "Report a Problem" links next to the items.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)

Playing music from Apple TV from iTunes not on same network?

We have a massive estate with Apple TVs and were hoping to be able to play music from our iTunes thru the Apple TV. We don't have computers in the main house, only in the office on a completely separate network (which I think we need to have with Home Sharing).
Is there a way to have Apple TV play our music content either from our iTunes on the Mac in another place? or from an iOS device? or from iCloud?
Any help is appreciated.
Thanks!

Home sharing will require both the Mac and Apple TV to be on the same network, there is no way around that.
If you have iTunes Match then you could access your full iTunes library in the cloud via the Music icon on Apple TV.
There is a feature called peer to peer airplay, that allows an IOS device to stream to Apple TV without needing the same network. However, this requires a 3rd gen ATV and IOS device from 2012 or later.

We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple.
What have you tried to fix it ? Have you tried closing the Videos app via the iPad's multitasking bar and seeing if it plays properly when you re-open then app ? Have you tried a soft-reset of your iPad ? If neither of those fix it then are you in a country where films can be redownloaded (assuming that it's not a rental) ? If you are then delete it from the Videos app and redownload it via the Purchased tab in the iTunes store app.
If you can't redownload it (e.g. if it's a rental) then try the 'report a problem' page to contact iTunes Support : http://reportaproblem.apple.com
If the 'report a problem' link doesn't work then you can try contacting iTunes support via this page : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

My apple RIP gives this error message" the application ppRIPe has unexpectedly quit"

MY APPLE RIP GIVES THIS ERROR MESSAGE" the application ppRIPe has unexpectedly quit"

Thanks.
I should have mentioned that I have already done the Resolving Permissions as outline on Apple Support pages, but, I went ahead and did the complete sequence as shown on Dr. Smokes.
I decided to stop beating a dead horse and did an Erase and Install of 10.2 again since I did not have anything on there yet. So far, everything is working perfectly. I am doing the Software Updates called for one by one to see if any of those caused the problem.
The only thing I did other than doing all of the updates after the install was to install OS 9.2 for my Classic Environment software and I also installed an HP PSC 1315v All-In-One scanner/printer. I cannot imagine that would have done anything.
I did have some strange issues with Where in the USA is Carmen Sandiego and The Star Fleet Technical manual so I may stay away from them unless I start in OS 9 if none of the other updates cause any issues.
Thanks. BTW, How should I rate your answer? I know that it did not solve my problem, but, it is likely that something else I did whacked something.
I'll update when I know more.

I have just installed CS6 Master collection but indesign isn't working, when opening I get the message "Cannot load Assignment UI.InDesign because it requires Username. Please install the Username plugin and restart InDesign." not sure what to do next?

I have successfully installed the CS6 master collection and all the programs seem to be working apart from InDesign. When opening it I get the message "Cannot load Assignment UI.InDesign because it requires Username. Please install the Username plugin and restart InDesign.". I have no idea what to do next?

Many people use a font manager to organize a large collection of fonts, and sometimes these cause problems in ID. You might not realize that the font manager has installed a plugin in ID, but I think you would know if you added any other program extensions to help you work.
Can you show us a new crash report since the 8.0.2 update?
What happens if you start the Mac with the Shift key held down to prevent extensions from loading? What happens if you go to the System settings and create a new user, then restart the Mac and log in with the new user?

Hello,
thanks for your contribution. But how I already said we have seen that the first error message:
The error is: javax.servlet.UnavailableException: Cannot load a validator resource from '/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml'
But behind that message is an additional message that describes the real root cause of the problem:
SEVERE: Cannot find resource "org/apache/commons/digester/xmlrules/digester-rules.dtd"
org.apache.commons.digester.xmlrules.XmlLoadException: Cannot find resource
"org/apache/commons/digester/xmlrules/digester-rules.dtd"
Unfortunately we have no idea why the dtd file can not be loaded. The appropriate line of code is:
getClass().getResourceAsStream("<link_to_resource")
And this returns a NULL object. The NULL object causes the general exception and finishes the instantiation of Struts.
Any additonal hints?
Regards, Maik
