Sorry OP, I admit I was just stabbing in the dark there. With all the combinations of cutters/software it's hard to say what anybody could possibly / inadvertently change in their settings to get undesired results.
I looked over some of your older posts and checked out Roland's website for some possible issues. Are you still cutting thermoflex with this cutter? Are you using enough downforce? According to Roland's website, "when cutting Thermoflex, you should be using a 60 degree blade and about 120-200 grams force". Have you changed the blade recently? How about the cutter protection strip? Did you just install the driver and immediately end up with this problem? I also read that "it could be that the carriage may need adjustment".
I make no claims to be a Roland expert, but I have been using their machines exclusively since I started out. If I ran into this problem I would check out some of the things I mentioned. If it just happened immediately after installing the driver, OP is probably right.
