I have an HP IMC Basic 50 node edition software installed from last summer and a valid paid license and it has been working fine for 9 months. It is installed on a virtual server Win2008R2 Std. and my hunch is that the MAC for the physical server is tied somehow to the license code. I moved this virtual a couple of months ago to another physical 2012R2 server, and the virtual server has not been restarted since. So, after an extended power outage, where I had to shutdown the physical before the UPS went caput, I booted it up, and all appears well, but when I use IE to get back into IMC, I get the Invalid license error code:50904. It appears possibly my license or something has gotten whack? The license file appears fine, but it's obviously not liking things. I went through the steps to download a new license and try again, but to no avail. Does anyone know who I can contact or how I can get a license that will work. When I go to HPE site, it says regular HP support helps for IMC. I can't seem to find a number or contact at HP that will get me where I need to be. If you know of a way to get help, it would be greatly appreciated. Thank you, ToneWalker
