xsun,
I *just* helped someone with this problem not more than 2 or 3 days ago, and after checking his log file he had numerous platform exceptions occuring and ended up reinstalling.

Lets try and take a look at your log file first and see if we can avoid the reinstall. It should be located at: <workspace dir>\.metadata\.log, please grab the last 2 or 3 entries starting with “!SESSION———-” and paste them into a message here for us to look at.

This problem has happened to my coworker a few times, she’s reinstalled to get rid of the problem, this problem has happened to her a few times. We would like to find the root cause of it. Here is from her log file. Thanks!

[Riyad Kalla]

You can try and remove the cache of the workbench’s config by erasing the <workbench dir>\.metadata\.config directory (or to be safe, moving it to your desktop out of the workspace dir).

I don’t see any terrible exceptions in the log though, does this happen every time?
