Datamaster not syncing very well.

PCM sync is intermittent. It will record, then stop, recycle, then record etc etc.
Have used AKMCable for 8 years. Now I have a new laptop, WXP 32 bit, same as last laptop that I used this software and cable.
COM3 is in use.
Device manager has USB to serial settings as
9600 bits per second, 8 data bits, parity none, stop bits 1, flow control none.

Advanced settings: receive and transmit 4096, latency time 1 msec, minimum read/write 0, and serial enumerator only box checked.

Datamasters settings: y car auto
Serial data acquisition box, when trying to record , Under advanced under options, Serial communication timing left to right, 180 180 500 and 1 (last is ALDL link timing.
Any idea where to start. Old laptop worked fine but crashed hard. New laptop is same OS, just newer.

SOLVED: Disabled data refresh and CCM handshake.
