Well I went went and installed over the old version.

Bottom line, the installation did not clean after itself.

My computer has a 128GB SSD drive for OS and it had 22GB of space left(yes a bigger drive is coming). I ran out of space during install, so I moved the "Songs And Lessons" folder to another drive. That freed up over 10GB all by itself. Then went back to the error window saying my drive was full and clicked retry. Sure enough, installation continued and completed itself. Now my c:\bb takes up 35GB of space not counting the 10GB I moved to another drive.

I guess the next move is to remove everything and start over hoping it works!!!
