Halion sonic instrument list no show

Can anyone help me?

I have a PC version of cubase running on 64bit. When I am in a project and I open Halion sonic, I am not able to see the instrument list. Then sometime after this it just appears (but sometimes not at all. Its as though its taking a long time to load or something. Shouldn’t do as the PC is high enough spec and windows 7.

Anyone seen this before

many thanks

UPDATE - now sorted thanks
