I just bought CS weapons and it loaded and I've flown the initial plane but when I try to use the loader to add to another plane I get Windows cannot access the specific devise, path or file. You may not have the appropriate permission to access the item.

I used open as administrator when I added the weapons and I also tried the same with the loader but same thing.

My FSX is on a external drive but it hasn't been a problem and when I added weapons I added it to that site.

Any help will be appreciated.
