groupError: 0 means there's no error (an error would be a non-zero return for groupError).
Here's one thing to check: are you running any software which is changing thread affinity for 3ds Max after you open it? You can check by running 3dsmax and then checking its thread affinity from the Windows Task manager. Every single CPU should be checked in the affinity window. Any modification to thread affinity can have a huge performance drop.
If you want official example scenes you can check the scenes download option on the tyFlow download page. There are a bunch that use a lot of grains (probably more than 60k in some places although I haven't checked) and none of them should take anywhere close to 30 minutes to sim through.
The latest BETA should basically give you full performance. I wouldn't expect any real performance difference between the BETA and the latest PRO for those scenes.
If you run through a few frames from the 30 minute sim from the tutorial you found with the tyProfiler activated, what does it show?
