ex.System.InvalidCastException

Hi, I have problem with moving workflow from one step to another step. I mean if i create a workflow with 3 basic steps (start, intermediate, end(positive)) on those steps i set up paths with task creation on business rule level and i set up myself (my account).
When I try to open that application in portal then on first step everything is ok and i can sent task to second (intermediate) step.
AND here is a problem when i try move task from that step or even when i try open task in Admin mode or remove task i get the same error with is:

What can be the problem here? I guess maybe something with the configuration but checked everything and it seems to be ok. Any suggestions?
