I tried, but I think I'm doing more harm than good. I used an old tournament, saved it to a folder, and did a manual import - but, it's taking forever and I assume not working. here is what I saved, $125 being the RB amount:

Full Tilt Poker Tournament Summary $14 + $1 Sit & Go (Super Turbo) (000000) Hold'em No Limit

4: Hurtch

That imports fine for me.
Are you using Build 5.2?
Have you saved it as plain text? (e.g. use Notepad)
