User referral - Mayor problems with the profile module

Thanks for developing this module but there are still many errors in it! By enabling this module, all entries of the custom profile module that are allready filled out by new members via registration form get lost! It seems, that this module won't handel this additional parameters and so we had to disable this module.

What we've already found out is that the module won't work perfectly with multilingual sites and clean URLs. Is there a solution for these bugs available?

Cheers,
AL
