Lived with the failure until I decided to add a new drive to the pool and re-create the array.
1 Deleted the configuration
2 Added te drive as a new PPU and formatted old PPU to act as new DRU
3 Tried to create and after 3 days got:

I have since: Deleted the config and used expert (was cruise control), Failed again, Installed different w_class1_0.dl per other forum posts, OutofMemory again, completely uninstalled and reinstalled FlexRaid, manually balanced DRUs (one was too full) and giving it a last chance. (Not much hope too since process flexraid.exe has increased its memory usage by 1000% in the last 20 hours) and it is stuck "reading" one of the DRUs and saving nothing in the PPU.
MB Intel, CPU Core i5, 12 GB RAM, Windows 10 Pro 64 Bits.
I really wanted to love this product... Too far from reliable and too far from set and forget.
