Well what a fun afternoon I had yesterday, it all started on the laptop with trying to add a basic title and getting the message in the attachment.
I knew I'd seen a post about this on the forum so dug it out and tried everything suggested and nothing worked, so i then uninstalled, rebooted and reinstalled.
On reinstalling I found that no sound effects were showing in the library, so dug out the post about how to get those back, once I'd got those back showing I carried on checking things out, and discovered, that HFX packs 1-3 were all watermarked, so back into search on the forum to find the post about sorting those as i couldn't remember what i had to delete to get those all showing and working properly.
Once I'd sorted those everything is now back up and running (thank goodness for the library backup and restore function).
It's a good job that I'm used to Studio and some of its foibles, and can find my way around the forum, can understand why some folk struggle.
