Oscommerce Expert Needed

We have an old ■osCommerce 2.2 MS2 store. I have just moved the site from a shared server to a dedicated server and when a customer goes to login from main page a 2nd page comes up with "choose user group" wholesale or retail. We had a wholesale section some 7 years ago and have not used it since but since we moved the site this extra login page is appearing. I imagine it is a button to check somewhere to not have this but I don't know where. 2. I accidntly deleted in the control panel when I was clearing old images a middle boarder image, so I need it replaced. 2. I also accidently deleted in the control panel a checkout image. I don't have the images but they are simply a colour match to what is there and the work "checkout" on one the other is just a colour. Simple job I just don't know how to do it. I also need it done today. Thanks
