I signed up and played both RPW2 and Jealousy, no problem.
I just tried to find other RPW2 endings and log in ok - I can play Jealousy - but trying to play RPW2 I'm just returned to log in and then told it's invalid. Same thing with Daughter's Friends, which I also replayed the last time.
I had problems with CCBill this time too - no login or pw email. My CCBill account details only showed login - I had to online chat to get the pw.
Not sure these are connected. It seems very unlikely but I feel Shark would want to be informed.
