Unfortunately - no backups - until earlier today, I could not find where the VST file was being saved. Now I know where it is, but I'm sure this version is the one with all the whiped out seeds.
But the main problem is that I don't know what the confict is with my PC - just that the saved seeds dissappear. No error messages - nothing to give me a clue.
The VST had worked fine for about a month - and now nothing, in any version of the VST I download.
I guess I'll just have to try and play the game the way it was meant to be played - only using the game seed trays alone.
