Realex Redirect Integration: Problem connecting back to the merchant's web site.

Issue Summary

Hi, Im hoping someone can shed some light on why this might be happening

This error has just started showing up after I finalise test card transactions.
"Your transaction has been successful but there was a problem connecting back to the merchant's web site. Please contact the merchant and advise them that you received this error message. Thank you."

Everything had been working fine up until two days ago. Processing the test card, sending back information about the order number, login details, etc...

I'm using Drupal 6.16, Ubercart 6.x-2.2 and UC_Realex 6.x-2.0-beta3
I have made no alterations to ubercart, drupal or this module for that mater that would/should of affected the processing.

I have been in contact with realex support and they send me back this log message and saying its something wrong with uc module.
