'Cannot load module file...' RM4.5

Warning: RM/Ruby newbie.

Using RM4.5 on Ununtu 10.04.4 LTS (Lucid)

I installed gems through Settings -> 'Ruby SDK and Gems'
The Gem shows up in teh list, 'require' does not give an error.
However, intelisense does not work, and I get the following error when opening the project:

Cannot load module file '/Dropbox/development/Projects/Ruby/RubyLego/.idea/RubyLego.iml':
File /Dropbox/development/Projects/Ruby/RubyLego/.idea/RubyLego.iml does not exist
Would you like to remove module 'RubyLego' from the project?

I already added  "gem 'lego_nxt'" to my code as per some other posts I found, but it still doesn't work.

Any ideas?

The error has nothing to do with gems. Please try deleting the .idea directory and using "Open Directory" on the same directory again to recreate it.

That did the trick!
Thanks for your help.
