Crash with 4.1b

[Blizz]

Hi All

After auto updating to 4.1b I'm getting crashes on loading any game system. A bunch of UI elements on the top left hand corner of the screen are all on top of each other and there's a dialog box with this:

HeroLab.exe has encountered an error and needs to close.

Here's a screen shot, in case it's useful for tracking down what's wrong.

Is there any way to roll back to a stable version, including the data files?

Thanks!

For the benefit of anyone else bitten by this problem I was able to work around it by:

1. Reverting back to version 4.1 which was in C:\ProgramData\Hero Lab\downloads
2. Taking advantage of the windows 7 filesystem to retrieve an older version of pathfinder.hl (in the same directory) and installing that (shame you can't download this from the website)
