Hi Michael.

I'm having the same problem. I installed MoI yesterday and worked with it for a couple of hours.

When Tried to open it today, I got the trial expiration message. I didn't change the dates and as far as I know no system upates where installed since I installed MoI.

I'm running Windows Vista Ultimate 32bit under an administrator account but with User Account Control active (i.e. Vista prompts me to greant admin-level access as required). I tried running MoI as administrator, but that didn't make any difference.

For antivirus, I'm using Microsoft OneCare 1.5.

Hope this helps, and I can't wait for the updated trial :)
