Logger Connection on Car

[sleepydsm]

sorry I didnt specify earlier: Its a 92 Tsi awd
I have a direct serial cable (no usb y-ed off) and it has a single red power wire coming off. When I bought the car, the dsm pocketlogger software was already installed. it got deleted when i changed batteries, so I used the supplied disk from the previous owner to reload the software. Now it doesn't display and numbers when in the logger software.
