A bug has found its way into the Midi_IO's trial verification engine.

Symptoms:
Crashes Quest 3D with a "Trial Expired" message whenever a Midi_IO channel is added to the editor or a project using Midi_IO is loaded after the 30 days trial period.
This bug only affects users for which the trial period (30 days) has expired - All other users (within the trial period or fully licensed) shouldn't be affected.

Remedy:
Just download the Midi_IO and re-install.

Please accept my apologies for the confusion this might have caused.
