FlashBuilder won't start

[Guest]

Using windows 7.

Starting via double clicking the executable results in the loading screen and then nothing.

SOMETIMES, when started via the command-line, a popup appears after the initial splash screen saying that "the workspace is currently in use", which suggests that FlashBuilder is still running - which it isn't.

When started from the commandline using the FlashBuilderC.exe I get:

C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)>flashbuilderc.exe

Exception in thread "Thread-5" org.eclipse.swt.SWTException: Device is disposed

        at org.eclipse.swt.SWT.error(SWT.java:4282)

        at org.eclipse.swt.SWT.error(SWT.java:4197)

        at org.eclipse.swt.widgets.Display.wake(Display.java:4873)

        at org.eclipse.ui.application.WorkbenchAdvisor$1.run(WorkbenchAdvisor.java:797)

Job found still running after platform shutdown.  Jobs should be canceled by the plugin that scheduled them during shutdown: org.eclipse.ui.internal.ide.IDEWorkbenchActivityHelper$4

Any Ideas?

Also, why is Abode support so bad?  I don't see many Adobe support comments on the Adobe forums and when going through the support portal http://helpx.adobe.com/contact.html?product=flash-builder&topic=using-my-product-or-service the phone number they provide isn't in use!!

I can't believe how expensive this product is for the quality it provides - my other post http://forums.adobe.com/message/5338632.

Did you ever get to the bottom of this? Flash Builder just crashed on my machine and now refuses to open—giving this error verbatim when I try to launch it from a command prompt.

EDIT: Google led me to this post, which mentions deleting the C:\Users\[USERNAME]\Adobe Flash Builder 4.7\org.eclipse.core.resources directory (see the 2nd comment by christoph). This allowed Flash Builder to start again, but I had to import all my projects (thanks, Adobe, for wasting an hour of my time today).

Thanks stenrap2.. Only an hour wasted?  That's good!

I did solve it yes - I did something similar to http://forums.adobe.com/message/4611386.

Although, I'm not sure why there's a cleanup tool instead of actually fixing the issues and costing developers time and money.

I just had this same issue.

I looked into what was suggested in the link Stenrap2 gave [removed by moderator], but instead of deleting the whole C:\Users\[USERNAME]\Adobe Flash Builder 4.7\.metadata folder, I went into there in .plugins\ and deleted the org.eclipse.ui.workbench folder and it allowed me to start Flash Builder up again without losing my projects and settings. I did lose the previously opened files, but apart from that, everything is there.
