I believe this is the same user that emailed us - he has already solved the problem. Thank you breezeking. Yes we do need a lot more info to duplicate the problem. In fact, when it involves 3rd party software, we may or may not be able to support...
In this case, the problem might be related with file/folder names of this format:
FILENAME .ext
The space before "." could have caused the problem. We will check further and fix it later.
