[Plugin: NextGEN Gallery] Getting NextGEN to work in subfolders – please help!

Hello,

I would really like to use NextGEN’s gallery in a folder called WordPress but I get errors everytime I try to do this. I’m trying to do site mock ups for clients on my shared hosting at Godaddy. I set each site up with a subdomain, then install wordpress in a folder. WordPress works fine, but it seems that this gallery plug in will only work in a ROOT directory. AM I WRONG? Is there something I can do to make it work in folders, such as https://www.mydomain.com/wordpress? Please advise.
