PC Charge Processing Very Slow

I am running PC Charge Pro with RMS 1.3 and I have been experiencing very slow processing times when I swipe CC's, I'm talking like 30 seconds each. The internet connection is not the problem. Settling
batches is very fast and the ability to browse the 'net is also very fast but for some reason, swipes are taking a very long time. I did some digging in RMS's Administrator and found a possible problem, but I'm getting a little beyond my comfort zone. What I found was, under the EDC tab in Administrator, the software that is selected is not PC Charge, but rather Preferred Acquirer. I figured that this may be the problem, but then I also thought that if the incorrect software is selected then I shouldn't be able to process cards at all. Any and all help/advice is appreciated.
