Microstudio2.613 I don't get Custom Assembly Tab

[Bobbi]

Help! It worked get in demo. When I Import CD+G to hard drive and it shows they are all Imported I am supposed to select Custom Assembly Tab at the bottom of the page (box). I did that in the demo and it was perfect. But after installing the real McCoy of a version, I no longer get that option. I have read and reread the troubleshooting and manual and I must be really dumb because as far as I can tell it should work. I really need to get this program working so that I can protect my investment.

I appreciate any help or tips I can get.

Thanks

Bobbi
