Mike,
The touchgate.reg is just a file that updates the registry from command prompt. Since you can login using any account suggest just opening the registry and update as needed. The 0 is to disable and 1 is to Enable in the registry. If you plan to update using the touchgate.reg , than can use
"TouchGate"=dword:00000000 to disable and "TouchGate"=dword:00000001 to enable.
Glad you got the system working.
