Filenames shortened

Hi,

I updated to Directory Opus 10 recently.

It's working great, except for an annoying problem.
After a while, say 3 minutes (i can't figure out what is triggering this), all files and folders get their names shortened to a maximum of 8 characters (all capital letters) in the right panel.
For example, "Directory Opus" will become "DIRECT~1".

Anyone could help?

Thanks!

That's usually caused by using a pirate version, but surely nobody would be doing that less than a week after release when there's a 60 day trial period...
