RTE 6 and RTE 62 when logging in are a result of a corrupted toolbar.ini file.

This issue is caused by not exiting out of MetalTrax properly before logging out of windows or before restarting your computer.

For Windows Vista, 7 and 8 operating systems:

1) Go to this location on the files system:
C:\Users\USER.NAME\AppData\Local\VirtualStore\Program Files\MetalTrax\

2) Delete the file named "toolbar.ini"

After deleting this file the "RTE 6 - Overflow" error will not occur upon logging into Metal Trax.

For Windows XP:

Go to "My Computer", browse to your C drive, then Program Files (x86) -> MetalTrax (or GlassTrax) and find the toolbar.ini file. Delete this file from the folder and then try logging in again.
