i not install that thing.. i need to install ?
are you talking about he little pop up that shows when you visit this web site http://mythos.t3fun.com/Home/Home.aspx
That has to be installed or the game wont start correctly.
If you have the beta version you need to uninstall it and install the new version of the game.
When mythos starts there is no log in, like bunnz said you only log in from the website link provided above.
1. delete mythos beta.
2. download mythos global.
3. install plug in from this web site http://mythos.t3fun.com/Home/Home.aspx
4. log in and click start.
5. launch mythos and enter New 6 digit
password as the closed beta accounts are no longer in use.
6. play and have fun.
If you still have error after you have follow those steps let us know.
