28202 need autosurf script fixed

ok to start off if you cannot do this job please do not waste my time this is not for someone to try and fix this it is to actually fix it the problem is our site is not automatically upgrading users with the alertpay addons everytime a user goes through the checkout it says invalid details and redirects the user to the homepage and does not upgrade them the payment goes through but no upgrade whatsoever we have followed the instructions on the addons we have which we have 3 different addons for alertpay which none work that is the first thing that needs done. the other is we need the users accounts to automatically activate as soon as they register alot of people are registering and not receiving the emails so to fix this problem we just want to have them automatically able to login. the last thing is we need this work to be done with the script we have but on your server we will not allow another programmer into our hosting panel or the db so this must be fixed and tested on your own server once it is fixed you will send us only the files that need updated for it to work and instructions on what to add to the [login to view URL] file if needed. wewould appreciate if this can be done quickly.
