Is anyone else's chat log passwords being stupid?? i've used the same password since i started and now when i try to open it, it says its the wrong password...then when i go into the messenger plus prefrences i change the password and it asks if i want to change the password from all my past log files...when i click yes it asks for the new password that i had just made, when i put in my new password it comes up with an error saying that its not a valid password...and it does the same thing when i try to un-encrypt them all...its driving me nuts and i really need into those log files...PLEASE HELP!!
