I have the above error, I didn't use character animator for a very long time (since preview 3), so I don't know when or what exactly caused the problem.. all other adobe softwares work fine (AE, Pr, Ps, AI..)
Windows 7 here
If none of those work, let us know your specs following this format: FAQ: How do I collect application and system information for troubleshooting issues?
2. logging out-in didn't help
3. uninstalling/reinstalling AE solved the problem!! heheh, never expected that.. many thanks
