Weird issue just came up.

I was running Tunerstudio latest version and wanted to run a datalog and then all of a sudden this came up. I tried reinstalling the tuner a few times and nothing works.

Fixed, If anyone has this problem or needs to really get rid of all the information due to an error. Use Revo Uninstaller Pro it will uninstall the application and then it will find the registry file you should delete, then erase these files in C:\document setting\your user name. Erase file name .efianalytics,tsMS,tsUser.properties. Then restart and reinstall Tuner Studio

Sorry for the late reply, I did not get notified of this post.

That looks like you changed the Language to something not supported on your computer. Windows 7 will work with most all the Languages, but XP often doesn't support that character set.

You could change back to English, but as the verbiage isn't there you would need to know to go on the main menu:
2nd menu --> 1st menu --> English

The Language names are always displayed in English.
