Help!! Problem downloading themes

[ledwards]

I just got a Blackberry Pearl a couple of weeks ago, I have tried several times trying to get a theme downloaded to my phone. I connect my phone to my computer and try to instal the application through the desktop software that came with my phone. I go to load application -> add but I can't get it to work. Everytime it says there is a syntex error in line one of the software. I have downloaded the newer version of the software and tried everything I know of. Does/did anybody have the same problems? How do I fix it?
Thanks!
