Dear Friend,

We just released a new update of MathRider - v4.01.043.

This update addresses an issue introduced by the latest version of Adobe Air, which has caused some users to lose their registration details, forcing them to re-register MathRider.

The new release includes a workaround that will prevent registration data from being lost. 

We've also fixed a problem that caused the quest mastery to remain at zero percent for the advanced quest.

To update, simply start up MathRider - it will automatically detect the new version being available and prompt you to download it. 

Thank you for playing MathRider! :-)

Best,
Thomas
