If you are having problems with an item after successfully installing and logging in the for the first time you should check your FTP software settings. I have found in many cases that numerous FTP programs are not uploading files correctly.
Check your FTP program to see if it is uploading files in ASCII - which is causing the file code to be uploaded in one long line.
Try changing it to Binary and uploading the files again. Upload everything except the install folder and the config file (or better yet, if you have not started using the item, just wipe the install and the database and reinstall a fresh copy).
I use CuteFTP for my uploads and ran into this problem when all of the sudden everything I was working on just seemed to stop working as expected.
