you are looking in right directory...
there you will find images.cr...
rename .cr to .rar and extract using winrar with this password
%3b%2a%30%33%7a%39%38%26%34%25%61%62%6b%33%33%30%33%38%34%37
now you will find many folders,open animation folder and you will see one more folder known as interball_overlay....
open it and delete the files...
now come back and cut paste all the folders you extracted in a new folder named images...
now cut images.cr file and paste it somewhere else but not here....
run the game(backing up)...
this should work but i haven't tried it yet...
if it doesn't work then paste back images.cr file to its original directory....
