Website issues

[Cam]

Hey Guys
While I am enjoying the new site I recently experienced some issues.....
All of a sudden I was able to login but could not do anything eg. could not post a message, I kept getting error messages saying I was l not logged in even though I was. This problem seems to have solved itself by making sure I logout first then login again
I recently tried to upload one of my scenarios to the data base. After filling out the from I got a " you have entered invalid parameters " message. I tried this twice and it would not work
While I am not the most computer savvy, I would appreciate help
Thanks in advance
