Quartus II 13.0 caught in infinite loop during compilation [12127]

Hey all,

I'm with one of the many University programs using the Cyclone II DE2 Board. Today, I finished working on a project, and after many rounds of debugging, it seemed like it would finally finish. However, at around 2% compilation, the compilation stops. The log currently says "12127 Elaborating entity "%name%" for the top level hierarchy." Compilation normally takes about three minutes, and this has been running for almost two hours now.

Here's the log:

Any ideas on how to fix this? I compiled and ran in ModelSim just fine, but unfortunately ModelSim can't blast the program to my board.
