Standalone 4.2.5 RC1 (64 bit): Crashes More Frequently Now

I have Vista Ultimate 64 and have for several versions now experienced frequent crashing of TLB Standalone 64. With the newest beta, the crashing has gotten much worse. I'm lucky now if it stays running for 5 minutes. The program just crashes, regardless of whether I'm using my PC or not -- just displays the 'Trule Launch Bar Host untility has stopped working' box, then it exits. Here's the info from the most recent crash:
