@update
Who were you using it on? I just tested it with
http://www.imvu.com/shop/web_search.php?manufacturers_id=198036300
and it worked fine.
Dowever I did forgot to erase the url I had the program defaulted to during debugging but that shouldn't be an issue. I updated the download link with the fixed source though.

I updated the code with some messages boxes to display any error that might arise for those who are having trouble getting it to work on some shops.
