I just check by using Mozilla fire fox because that is what I use to log in to PIF admin, and I didn't have a problem logging in like a webmaster to Topbucks and or using any of the tools or unzipping any Files?

Will make another effort by asking one of our techs if there is something that should prevent others using Mozilla of doing the same.

At any rate I would say use IE and if you don't have access to IE then please contact me directly with which exact downloads and banners you want.
