Running RB 2015 for the first time on this new Toshiba laptop. (BIAB 2015 works fine with it.) Started with RB 2015 build 2, running it from the Audiophile drive. Went through the setup process, told RB where the bb, RealTracks and Drums folders were located, chose my ASIO and MIDI settings, etc.
Entered some chords, knocked it down to about 8 bars just to try out some styles. Clicked the Style drop-down, then StylePicker. Yellow dialog box says "Initializing accompaniment functions... please wait". Fine. StylePicker opens, and I pick a style and click OK. So far so good. Song generates fine, and I want to try some more styles. Problem is, if I now go and click StylePicker, nothing happens - or, I should say, something happens that causes RB to freeze up indefinitely. Can't click on anything (I let it hang there for 15 minutes to see if it would snap out of it - it didn't).
Task Manager to the rescue once again, which causes RB to generate two duplicate dialog boxes asking whether I really want to interrupt what RB is doing. RB CPU usage is about 25% while this is happening. Also, this freezing also occurs when, after successfully opening the StylePicker initially, I then click Filter. Immediate freeze, and after forcing a shutdown of RB, the still-frozen StylePicker window remains, and I always have to have Task Manager stop the bbw2.exe process to get rid of it. Oh, and from that point forward, any attempts to re-choose ASIO will result in an "access violation at address 055325A9 in module 'Rdaw1079.dll'. Read of address 00000108" error, and I'm stuck with the MME driver.
Other than that, everything's great.

Any thoughts? BTW, updating to the latest build (8) didn't help.
Thanks.
