Altera Monitor Program hangs

Honored Contributor II

Hi I'm trying to use the altera monitor program to debug. 

But it hangs while I'm loading source code. Here's what It says in the Info and Errors message box:

I don't see any assembly and most of the menu options are disabled. It used to work before, but now it just hangs. Can someone tell me how to solve this?
