Version 2.4b (923)
Does this always happen? Do you have write permissions for the file? Can you reproduce it with the file?
Happens always on the file, I have read and write permissions. I can’t send you the file because of non-disclosure…and I can’t run Disguiser on it because I cant save 
can you open and save it in an older version? Maybe 2.3-895?
yep it worked, but still doesn’t save in Version 2.4b (923) i’ll send it to you
