For some reason, I cannot run any commands after loading psscor4. I downloaded x64 from psscor4 from the MS website and put it in the same folder where windbg is located. Before loading psscor4, I can run sos commands without any problems.

As soon as I load psscor4, I cannot run any sos commands

I can run these commands after the sos prefix. So! Sos.do works great. But the problem is that I cannot run any special psscor4 commands. Any idea what could be wrong? I think the psscor4 output error is misleading since I don't think any GC happens when I attach windbg to this process.
EDIT The following is the configuration used for .NET 4.0. Which one could be used with psscor4?
