logic express 9.1.1 won't work in mountain lion, 8 does!

Just upgraded to ML. I don't use Logic much, hence only having Express. Annoyingly I assumed Apple would support its own product but no.

Anyone know how I can upgrade to 9.1.7 which is supposed to work?

Meanwhile I found v8.0.2, which I had when I upgraded to 9.1 and works in ML... what's that about?!

I looked in the applications folder to find v8 sitting there waiting to be used! There are some issues and it opens a default project with the warning it was created with a newer version (true!). Warnings on loading are...

1.

Dear Logic Express user,

you have 1 Audio Unit(s) enabled which did not pass the Apple AU validation. This may cause problems and can even crash Logic Express or lead to data loss! Please check with the manufacturer(s) for updated versions. We recommend disabling these plug-ins in the AU Manager.

Warning! This project was created by a newer Logic Express version.

This may cause problems.

Please update Logic Express.

Wish I could, ironic sense of humour, Apple have

Logic Express: Plug-in “Pedalboard” not available!

4.

Logic Express: Plug-in “Amp Dsn” not available!

And that's it. I've opened a file made in 9.1 with just the warning 2 above bounced the file ok - and played it to check.

I assume you'll have a problem if you've used the plugins that aren't supported, but if not you'll be able to work.
