I don’t know what is causing this error or how to fix it but Flex Builder won’t start up.

I found this online but I still get the same error.

UPDATE: I reinstalled Flex Builder 2 as JabbyPanda suggested and I’m now back in business. Not sure what the cause was.

    On my OSX installation, I am able to fix this be deleting a hidden file titled “.lock” from the workspace directory (and maybe the project’s directory, I don’t remember). Works like a champ. Frustrating as heck, though.

    Thanks. I am on PC. I tried to find a lock file in the workspace directory, “C:\Documents and Settings\Judah\My Documents\Flex Builder 2\” but did not find anything there. I found a .lock file in “C:\Documents and Settings\Judah\My Documents\Flex Builder 2\.metadata” but I still get the error.

    Hi,
    You have to find a file named .snap under your documents and settings folder/Flex Builder/.metadata/.plugins/org.eclipse.core.resources and delete it.It happens only for the reason when you try to open multiple instance of the same application.Try doing it.

    My problem was related to files that I had open in Flex Builder, it would start, then I could see it re-opening my files and it would crash with the same error. The log file had a bunch of useless junk in it.

    Here’s how I fixed it:

    Go to:

    My Documents\Flex Builder 2\.metadata\.plugins\org.eclipse.core.resources\.projects\

    In this folder you will see a folder for each of your projects, go into each one and delete (or rename) the “.indexes\properties.index” file – this file tells Flex Builder 2 which files you currently have open.

    Hi Steve

    My problem resolved after delete properties.index file from selected project
    Thanks

    I tried all these fixes and none of them worked. The fix for me was to rename a file. My css file has the extension .CSS (capitals were the problem). When I renamed it in lower case the error was solved.
