824 killed my installation of RubyMine Follow

Nuked everything that had a name rubymine on my disks except one 820.dmg that I had downloaded earlier (a working version), emptied the trash. Installed from this dmg 820. Cannot do any file operations (new, open...). Cannot even set the SDK.

Tried the same with a new download of 824.

Hello Hannu,

I was happily running RubyMine 820, worked just ok. Decided to upgrade
to 824. Now I cannot open any project, directory or even create a new
file. Tried going back to 820, same thing. Tried nuking the rubymine
preferences directory. Same thing.

You need to use File | Invalidate Caches on the RubyMine welcome screen and
then restart RubyMine. Sorry for the inconvenience - RubyMine needs to be
able to recover from such situations by itself.
