iGO Missing Settings button to change language

[cloneman]

my iGO is missing the settings button to change language (no-name GPS running mediatek WinCE 6.0)

How can I reset iGO or reinstall it

Try renaming or deleting the folder named "Save" in iGO's main folder.
That will reset all settings back to default, iGO will create a new Save folder auto when the program starts again.

Are you saying you had the button initially and then it's gone? If this is the case you need to reset to default.
If you never had it you might have weird skin installed. A;ways can try to use a different skin.
