Poker tracker has been inaccurate lately.

[Pinky]

I've been using it for awhile. Lately, it's been under-listing or overlisting some of my wins ranging from $50-$150. I know I'm not making a mistake b/c it gives an accurate count for the number of played hands. I even wrote down my before/after cash balance before playing and inputting stats and still have this problem. Started about a week ago? Any ideas?
