(I suspect this will be in vain ... ) To all those asking "
i cant login in what can i do?":
First read through the last few pages of this thread, it is very unlikely that you are the first or only one that are experiencing this issue, it might just happen that someone has already posted a solution, and you will find it among the posts for the last few days. Which is true in this case.

In my case i had to update line 102 in CommonFunctions.py to fix the "Script Failed!" error, then download and update to 3.4.0 (beta?) version of the plug-in (
clicky) to fix the login in problem.
This is on XBMCbuntu (11.10, Eden).I think this issue is OS independent, so basically just update the required files (make a backup first) and you should be all set.
3.4.0 also fixed the login issue on my Raspbmc
