Need authentication fix for Jomsocial registration

I am running a Joomla (1.5.14) community with Jomsocial (1.5) as social component. The registration goes through the Jomscial and users experience an "authetication" error, which preventrs them to continue the registration. The error message says "Error on getting authentication key!" I tried it myself with "dummy" accounts and encountered also the problem - not always - just sometimes! I? need this problem fixed within the next 3 days! I cannot grant you access to my server so you have to do it on your test environment and just send me the instructions/code. ## Deliverables I am running a Joomla (1.5.14) community with Jomsocial (1.5) as social component. The registration goes through the Jomscial registration site (because I need all the personal profile info etc.). However, some users who want to register complaint that they cannot register, because already on the first page (email, username definition) they receive an error message when they hit the send button. The error message says "Error on getting authentication key!" I tried it myself with "dummy" accounts and encountered also the problem - not always - just sometime!s. I discussed it in the Jomsocial forum already and nobody could find a solution. They say that this might be a conflict between Joomla and Joomsocial authentication. Because I spent hours and days to fix it myself, I am willing to pay 100USD if this problem is fixed within the next 3 days! (of course the lower the bid the more likely I accept) I cannot grant you access to my server so you have to do it on your test environment and just send me the instructions/code.
