failed to install gem required for stock debugging

I'm dead in the water, can't even debug a simple hello world type of thing. Maybe I mucked up my install. I installed to USB and changed my idea.properties as suggested. BTW, I'm running on Win 7 Pro 64 if that makes a diff.
thanks in advance.

-----------

I get the following error upon attempting to debug which attempts to load a gem required for stock debugging. See here:

Version:0.9 StartHTML:-1 EndHTML:-1 StartFragment:0000000111 EndFragment:0000006109
