Problem with RadLog graph

I've been fighting a problem with RadLog Professional graph. When it draws a graph, after the first four or five plotted points it erases the oldest point so I never see more than 4 or 5 points plotted on the graph at any one time. When I first installed the program it worked fine but after closing out the program and restarting the next day the problem showed up. I removed the program and reinstalled and it started working again, but when I shut it down and restated it showed up again. Then after a couple of attempts at fixing the problem it started working again, then it quit again. I went through the disk drive and removed everything related to RadLog and Radmon and reinstalled the software but it is still not working properly. I tried just installing the Lite version but that doesn't work either. Does anyone out there have any suggestions, I'm open to any suggestions?

I don't know how this posted here ( I probably screwed up), but anyway I reposted this in the proper place in the software section.
