You were given a 90-day demo license key for evaluation purposes and want to know the PacketShaper's behavior once the 90-day demo license key expires. 

If a license key is expired, it will cause the PacketShaper to reboot at 00:01:00 GMT time on the expiration date no matter what time zone you set on the Packetshaper.

Note: This is expected behavior and applies to all the keys including acceleration, compression, control, linksize, and so forth.
