Corel Painter Error 38 - re-install from original media

I'm posting this here just for information and in case anyone searches the forum for the error.

Our street had a powercut last night while I was using Painter and this morning when I tried to launch it again I got the "Error 38: re-install from original media" (or something similar). Rather than go through a re-installation, I restarted Protexis Licensing in Services. It appeared that the powercut stopped it running. Painter launched as normal.

Windows 7:-

Click Start.

Type Services in the Search box.

In Services, scroll down to Protexis Licensing.

Click Start Service.

I suggest to anyone who gets a "re-install from original media" warning to try this first.
