Bugs and glitches stopping me using Notation 5

[nikone3na]

I bought the new version 5. It seems to be full of bugs that basically stop me using it.

Firstly, I click on new song, it tells me Harmony Font is not installed. I then install Harmony font. I get the same message from Notation when I try again. When I decide to re-install Harmony, it tells me it's already installed. I overwrite it anyway and install it again, and try to create a new song, and the same thing happens.

Can anybody please help with this? I can't use this software at the moment - it is more or less useless.

My second issue is with using drum sounds. I can't get any from the main menu, except when a non-drum instrument suddenly makes drum sounds. Again, this is ridiculous. I can't find the drum sounds to write drum parts, and yet have to get rid of them from eg violins, etc.

Once again, this is resulting in me getting virtually nothing done.

Any ideas, anybody?
