I initially downloaded the application and was able to gain access to all of my photos through album, photostream, fb, etc. Now it will not pull any. After deleting the app and attempting to download it, it says I must pay for it (again) any help would be appreciated.
Sounds like a verification issue on whatever marketplace you bought PS Touch from. Did you try contacting Google or Apple to see what they say?

My start got into my computer and i cant access my emails, can you help?
My start got into my computer as my browser, and it wont allow me to access my emails. Can you help me remove it from my computer?
First, try to reset Firefox. [[Reset Firefox – easily fix most problems]]. This simple step will eliminate many Firefox problems with only one click.
A few other basic trouble shooting things you can try is this:
Run all Windows Updates, install all needed service packs, etc.
Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.
After all these steps, make sure you update to Firefox 14. [[Update Firefox to the latest version]] -

Problems with SwingWorker and classes in my new job, ;), can you help me?
Hi all, ;)
First of all, sorry about my poor English.
I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
I have two classes:
Form1: Its a JPanel class with JProgressBar and JLabel inside.
FormularioApplet: (the main) Its a JPanel class with a form1 inside.
I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
In Form1 I make a Thread that update the progress bar and gets the fole from the server.
In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
THE PROBLEM:
The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
I put in bold the important lines.
Note: My level of JAVA, you can see, is not elevated.
THANKS A LOT

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Can you start Firefox in Safe Mode?
You can use one of these to start Firefox in <u>Safe Mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
*https://support.mozilla.org/kb/Safe+Mode
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
