***Please*** Help me

Hi,

I had the 30 day trial period installed on December 13th. My entire members area and other products are linked to this script and just when we worked out all of the minor glitches, today... the entire system shut down and I get this:
The encoded file /home/articleb/public_html/a/amember/member.php has expired.

What does this mean? My programmer is out of town and I have no clue what this could be.

I would appreciate any help you can on this Friday night.. thanks.

Regards,

Mike
