After Effect CS6 Crash

After almost 6 month, my firewall is open, so anything can come in. in midlle of project the Ae get crash, and its the Ae CS6 only.
I try to uninstall all, then I try put the amtlib.dll back. Install back again also not help.
I try to copy at the Ae.exe file, seem working in safe mode. but still not in normal mode.
Curius about the adobe dynamiclink.dll, I try to copy also. but not working.
Need uncle google to listing all the problem.
