I'm having the same problems, just emailed Jan Swartz.
I too called in a couple of times, transferred around, and was told to create a new account, but be sure to enter my information exactly as it was in the existing system. Well guess what, I'm not sure if I can't see it.
This is absolutely disgraceful of Princess/Carnival to have these ongoing IT issues, and you can never get to someone to fix it. I'm not going to try creating a new account and hope that I input the information to match only to find out that I didn't, and now I have a new captains circle number, can't see my booking or FCC's, etc.
