Okay, wow, extremely frustrating. I'm going to try and summarize everything as best as possible. After installing snow leopard I've had constant issues with mobileme, first with data conflicts, after I choose which data I think is correct (I usually guess) it then (sometimes after several minutes) constantly props me for a password. It's constantly saying this: It says this WHILE LOGGED IN, I've logged out a million times and logged in, the password is correct. After I log out and try to log back in, it also gives me this error: If anyone can tell me how to fix this problem I'll buy you an iMac, this is so frustrating. Thanks.
