What can I do to fix this?
There used to be some trouble with Animated Gif but I believe they were sold already. Try to select the file and with right mouse click use option to purge cache for selection. Otherwise check another animated gif if it has the same problem.
Tried that and I'm still getting the same error message.
Did you solve this problem? I'm having the same problem in my BridgeCC when selecting gifs. Help :-)
