Rule 1 NEVER DELETE FILES from your system, as some files will tie into registered programs and by deleteing one of these files can cause major headaches.
   The only sugestions I can give you are If you are using windows XP or windows ME you can do a restore back to a point before the problem. If you are not sure on how to do this just check out the windows help file it will show you how to do this. If you have some other version of windows you more or likely will have to download the package again you probaly deleted the ini file for TTools. Check your recycle bin you might get lucky and find it there unless you emptied it.
