Install 1/2 mods on my zencart website

I have installed many mods on my website in the past but I wanted to install a mod that allows me to place orders through my admin interface so i can process telephone payments. The moduel required me to install edit orders 4.x moduel first so i did this. When installing the edit orders mod i got to the last few files (auto loaders i think) and it made the login for my admin dissapear so i removed them. After this edit orders seems to be working fine even though ithought it did not install properly. As i though it seemed like it was working i then installed the other mod for putting orders through as an admin but when i finished uploading all of the files it comes up with an error Error "Error: Admin New Order requires Edit Orders 4.x. You must install a compatible version of Edit Orders before the installation will continue!" This maybe due to not installing the firs mod correctly. Im sure i installed the correct version for zencart 1.5.1
