We are pretty sure it has to do with firewall software and there is a way to set it so this won't happen. Mainly, you need to set it so you "accept cookies."
Try looking in your "options" for something like that. If that fails, get back to us with all your info: Operating System, Browser and version of it, any other recent software installations.
The following was also posted by a Forum User that discovered his problems:
"First off all, your computer has to accept cookies.
Second after you clear your internet History/Temp-files and or Cookies you have to log in again after you have restarted your computer.
Some computers do clear temp files and cookies automatically ( Pest Control program or Clean up program ) Be sure that this is not done automatically and you will not have any problems logging in each time you visit the Catsailors pages."
