I have been playing MXO for about a month now and this afternoon, when trying to log on through Station, I am getting a login error message.  It states the following:

Authenticating...Failure.  Incompatible client version.  Please quit, restart, and retry with "Full System Check."  If problem persists, click on the support button.

Here's the kicker...  I set the full system check feature, quit, restarted the computer, the station, the login authenticator opens up...the full check isn't done...and I am getting the same message...to boot, when I click on support, it sends me to a page that says operation failed, illegal parameter.

Does anyone have any suggestions? 

Thanks in advance for any help.

From over here:

This should cover all cases for people who logged in today with Station Launcher and then encountered these authentication issues:

1) Run the game by double-clicking the "launcher.exe" file in the directory where you installed the Matrix Online.

2) Click the "Full System Check" switch under the launcher's main display panel where the EULA is displayed.

3) Click "ACCEPT." This will patch your launcher.exe back to the correct version (7.5658).

4) Once patching has finished, click "RESTART," or wait a few seconds and the launcher will do it for you.

5) On the restarted launcher's EULA window, click "ACCEPT." This will take you to the launcher's Account Login window.

6) In the login window, click the "Full System Check" switch under the main display panel again.

5) Enter your game username and password in the main display panel above the switch.

6) Click the "ACCEPT" button. This will patch your client back to the correct version (7.5658).

7) Once patching has finished, click "CONTINUE" to go to the character select screen. You should now be able to pick a character and get into the game world.

Looks like the Station Launcher patch files have been set back to the correct version, so running through Station Launcher now should work okay.
