Oscommerce Messed up needs fixing!

My webhosts decided to move me to new servers for some reason, and since then all hell has broken loose. First the shop disappeared which i fixed, then i got errors which i removed by updating the config file, but now i am getting orders with no payments, so i go to look, and when i go to the modules section when i click on payment all i get is this: Module Directory: /home/2/c/d/2095/2095/public_html/catalog/includes/modules/payment/ and similar for the shipping module. I think everything else seems to be working, but i have a custom skin and 50 or so products, so i don't really want to do a clean install. Looks like the payment and shipping modules got messed up, and i'm fed up of tweaking, can someone sort this out for me who knows what they're doing??? Thanks!
