Windows XP file uploader and registry edits

Windows XP file uploader and the registry edit.

I am attempting to host gallery 2, as a multisite.

I like the windows XP image loader. but I am having issues.

It will allow me to register only one of my sites. when I register the other site, it overides the previous one, so that I can only use the windows xp loader on one site.

am I missing something.

can I edit the registry information?

thanks in advance.
