I was unable to login to the new store today when trying to by Synthetic Dawn. The interface helpfully informed me that "6-128". I am guessing this was about password length, but as my password was 30 chars this felt like a bug. I had some spaces in my password that a script probably didn't like so I tried requesting a password reset to fix this. After about 20 minutes of waiting for a reset email I went to the forums to see if someone else was having issues and was there able to log in using the old interface. I requested a password reset that I got immediately and was able to change the spaces to dashes and I could then successfully log in to the store and complete my purchase. Perhaps not the smooth shopping experience I was expecting but I got there in the end.
