            We've been using UoN successfully for some time, and upgraded successfully in the past too. When I upgraded the server side this morning it seemed to go well, but the license code was rejected as not able to work with this new version.   In addition, 4 or 5 of the dongles required installation, most did not. Of the ones that required installation, any attempt to install them resulted in an immediate hard reboot of the computer. The only option that did not reboot the computer was to cancel the install of the dongles.    The resulting installation worked okay with clients, but only those dongles that were discovered automatically and required no installation. I've not sorted out which ones they were yet as there are 12 or 14 of them.   I reverted the server software to version 4.4, and all the dongles were again recognized with out need for installation, and serving of licenses resumed normally.      The computer is as follows:   OS Name:  Microsoft Windows XP Professional   Version:  5.1.2600 Service Pack 3 Build 2600   System Manufacturer:  micronpc.com   System Model:  PT84510A   System Type:  X86-based PC   Processor:  x86 Family 15 Model 2 Stepping 4 GenuineIntel ~2392 Mhz   BIOS Version/Date:  Intel Corp. PT84510A.86A.0021.P03.0202251254, 2/25/2002   Total Physical Memory:  1,024.00 MB   Available Physical Memory:  530.85 MB   Total Virtual Memory:  2.00 GB   Available Virtual Memory:  1.96 GB      Thanks for any insight anyone might have on this issue.
