I am trying to use funcap plugin in IDA pro 6.1. However, after loading the plugin (with Alt+F7) and pressing the debugger's run button, it returns me:

Internal error 30191 

Any idea what is the problem?

P.S.: I have tried with both Python 2.6 and 2.7.

By any chance do you have the IDAStealth plugin installed? If so, do you have SEH debugging support features enabled?

As per the bugfix for the plugin:

Bugfix: If any of the SEH debugging support features was used an "internal error 30191" would be raised in IDA as soon as the exception occurred in the debuggee
