I have been making numerous changes to prevent GraphSynth2 from crashing. It has already run fine on my machine and have wondered why it didn't work on others.
If you've tried this software before and given up on it because it crashed, please try again and/or let me know what agony you faced. Also, I am happy to receive the ErrorLog.txt file, now found in your C:\Users\\AppData\Roaming\GraphSynth folder.
Some interesting patches:
