Default people using datamaster come in please

First off ill start by saying i scaned my car a bunch of times and it worked fine. Now i did a lot of work and now i go back and scan it and im having all sorts of problems. First it wouldnt reconigze my PCM, but i got all that figured out but now when i am logging i get the "DATA ERR." flashing in the top right corner and i cant record anything right. They said youll get that if you have bad grounds but i checked them all and there good to the eye. What the hell?? What can i look for... anything else i can try?? Im running out of free scans trying to figure it out.

Is the cable setup on the right COM Port? My USB data cable on my laptop uses COM4, and sometimes defaults to COM1 or no selection, and I need to set it again through settings. This is with TunerPro, but I used to use Datamaster and it is the same concept.

I would check the options and try different COM settings if you have problems connecting to the cars computer.
