HELP! Broke LIVE STORE

I was trying to install the new Paypal IPN 2.6 module, but decided not to, so I restored a backup of what I had, now it gives me an error for the Payment Module page. I have replaced the whole admin side of my site, so I dont know why I am still recieving these errors!

well 1st of all i hope the above problem was solved by now, but if not, heres my 2 cents....

Warning: main(/home/nyapwil/public_html/catalog/includes/languages/english/modules/payment/ipn.php): failed to open stream: No such file or directory in /home/nyapwil/public_html/catalog/admin/modules.php on line 129

the 1st warning is most likely triggering the second n 3rd n so on warnings,

/home/nyapwil/public_html/catalog/admin/modules.php file must have some kinda call/include for (/home/nyapwil/public_html/catalog/includes/languages/english/modules/payment/ipn.php)

if you are on *nix server, try using the "grep" function to look for "ipn" string n see what files are associatiing themselves with that string. that might a good start....
