After successfully installing the trial version of PRTG, set up multiple sensors. Before the 30-day limit, I reduced the number of sensors to below 100 (currently 91). After the 30 days, it continued to run for a couple of weeks. BUT now it says Disconnected for the Status of the Core Probe\Server and no data is being collected. One installation on one physical server, Win2003 SP2 32-bit. Please advise on how to fix this where it will run the stated 100 sensors or less for the stated FREE of charge for the stated period of FOREVER.
