malaikkabir I've moved your post to a more appropriate place.
I'd appreciate in the future if you wouldn't use caps (CAPS FEELS LIKE YOU ARE SCREAMING), it is generally badly considered on forums.
Considering your problem i'm not sure I can't be helpful for now but I'll try to give some clues.
You said that you reinstalled CC on a new computer. Did you also reinstalled the custom plugins you might have installed on the old one ?
I'd suggest you to post the problematic .cap nevertheless so that other might try to open it and tell you what the error is.
