Hey. I am having a bit of trouble with the download module. I have been having trouble adding new Main categories and Sub Categories. So far I have 6 main categories and I want to add 1 more. When ever I try to add a new Main or Sub Category it doesnt add it. I will attempt it again and again but it wont work. But when I add a category with something like "asdasfasd" it will add it, but even when its added, I cant add or modify that category.

Can anyone please help me asap?!
