Here is, once again, a good reason to use GOOD, SECURE passwords - not common words, names, or similar. Never share your password with anyone. If you forget it or if you find out its been used by someone other than you - change it. (PC has a password reset feature - use it) Lastly, always use a valid email when signing up to password protected sites, like PC, so that you CAN recover lost/changed passwords.
a good password will look something like Gdb$29^sHhgk)1Jle_z7A i.e. ramdom upper/lower case letters, numbers, and various other characters 8 - 16 characters long (longer is better).
