Just tried it myself. Import Wiz does not work with the 2.0 beta test, but reverting back to original at eBay should work.
I was able to import from my watch list. Don't know about items bidding on as I don't bid early in auctions. Are the items you are bidding on ALSO in your watch list? You might try that. You can also file a support case at: http://support.auctionsniper.com/
Personally I use AS's 'Snipe it Now' from eBay most of the time.
... and WELCOME to the forum.
