Reactions Beta not working

Hi Jascha,
I have download the latest Reaction Beta and installed it in cinema4d R23,24 and 25 and both of them hangs when i load for example the Explosion under Templates/Volumes. When i start Reactions standalone, after short time it hangs. When i look there is no Crash logfile saved
My Machine:
Intel(R) Core™ i7-8700K CPU @ 3.70GHz
GPU 1: NVIDIA GeForce GTX 970
Windows 10 64-bit

Do you mean the file %HOMEPATH%\ReactionsData\reactions.log does not exist? If it does exist, please send it. It should have been created as soon as the standalone started.
Thank you.

Hi Jascha, today i try a GTX 1070 8Gbyte with Reactions and voila its works without crashes and hang.

Thanks, Lars. Could you still send the log file from the machine with the GTX 970 when you get a chance? It might help resolve the issue.
