Hmm, strange! I don’t know what the answer is, but I recommend posting a thread here:
CGTalk Support Forum
http://forums.cgsociety.org/forumdisplay.php?f=79
Bear in mind that the webmaster is in a different timezone (Australia) but if you post a thread and subscribe to it, you are likely to get an answer. 
Sometimes I have problems with my preferred browser, Firefox, and have to switch to IE temporarily to post replies. I don’t know why this is, but Firefox usually works 95% of the time. 
Enrique,
Fantastic to see you back, and I can’t wait to see what you produce! :bounce:There are no jerks this side of the Forum, so no worries.

Cheers,
