"Parameter is not valid" exception on Windows 7

My office just updated our computers to Windows 7 (64bit). Previously, I had been running ANTS Profiler 4.3 on Windows XP with no problems. Now on Windows 7 I'm getting this exception after I click "Start Profiling":

Parameter is not valid.
System.ArgumentException

It seems to happen regardless of what I am trying to profile. I am running the program as an administrator. Any help would be greatly appreciated.
