Some of these are very easy to fix. For example if any of the files in !Clickx2 are deleted the program will crash with an error message and you will not be able to get anything meaningful done. Check all the files are as shown by clicking here.
If all the files are intact and everyone has the same problem you will
need to contact the programmer for help. If the problem is only
occuring for some people it is very likely that copying files from working discs will solve the problem.
