I bought the 2009 version of BIAB but immediately had a problem, in that when clicking S and going to "Bar settings" and then clicking Style or Open and choosing a style and clicking OK-OK, no style is registered (and no box appears at the bar number). At the same time "Redo delete bars" appears on the edit menu even when no bars have been deleted. I have found this happens in any song.

As this makes it impossible to do what I want to do, I would like to revert to BIAB 2008, where I had less significant glitches and could work around them. To revert, do I simply reinstall 2008 from the disk or would that cause other problems?

Grateful for advice.
Chris
