PayPal has been having problems with their API, and the recent requirements for the accounts that they allow to use it.
You need to have a 'Verified' account account with them, and then you will need to call to get a specific authorization code to use in the module.
I have the module installed on three or four sites and it wokrs without fail...however, when any of my clients change their accounts at PayPal I end up having to call them and have everything reset again. They have as much as admitted the problem is theirs, yet they still have not published a fix or standard resolution to the issue
Have you tried the module?? If so, what issues are you having?
let me guess...it doesn't report the donors?
