Thanks. I think you are perfectly right about the 64 vs 32 bit.

The tuner in BIAB is not very good, and it's a pity. But the situation reminds me, that I recently bought the everything PAK, and realized it was not everything, if I didn't pay a little extra.

Anyway. If you know about any free software which makes it possible to use 64 bit plugin outside RB/BIAB, I would be glad to know.
