From Mike:
I apologize for the recent 'expiration' and confusing upgrade message with this version of MileTracker. I promise that this was unintentional. I completely forgot that I had long ago configured it to stop working on June 15.
There are two workarounds at the moment: 1) Install DeskPort which includes a fully up-to-date and functional version of MileTracker (see the May 28th message below) or 2) Set your computer's clock back to before June 15, 2004 before running MileTracker.
I'm close to completing discussions with another company that will allow me to offer a standalone version of MileTracker in the very near future (late July?). Please be patient and consider trying DeskPort, which I also wrote, until that time.
Late July!?!? I don't know if I can make it

Seriously, though, I am glad that the possibility (probability) of a standalone version is still alive.
