Unsupported file format?????!!!!!!!!!

I recently upgraded my script to 1.3 and everything has been great because ive been using the embeded game feature as apposed to the upload game feature. Recently i tried to upload a SWF and it's now saying "Unsupported file format"!
Help! ive been trying to fix this and I can't figure it out

could you send a copy of the swf you were trying to publish, thumbnail image, config.php from the "include" folder and "content.php" from the "admin" folder to support@proarcadescript.com? Most likely having those files I'll find the reason of your problem

Problem solved. It was my own fault..
I deleted a section of code by mistake.
