Project just blew up - Cant Compile in IDEA: "Error: Read from Storage 0 bytes ..."

After using IDEA for many months without a hitch, this morning I had a hard crash on a development server. When I rebooted and tried to continue developing the project to my horror I found that IDEA now wont compile the project. It returns:

"Error: Read from Storage 0 bytes, but requested xxx bytes"

I tried invalidating all caches, as suggested by another thread, but that didnt resolve the issue. So I also tried to completely delete the cache files in folder .IntellijIdea90/system/cache/* Still the same problem. The log file from the most recent attempt contains the following:

java.lang.Exception

I have tried searching the entire file store for fileColors.xml and groovyc.xml but they dont exist.

Can anyone please help me solve this problem. Until I do my entire project is in the dumps and on hold.

Thanks hugely,

Roger
