I have been using the xcelsius 2008 server trial edition and decided to purchase the full product. After I paid, I received a product key and a link to download. When I open the trial version, it has a link to enter a product key, so I entered the key I was given. I got a message that this key was invalid.
So I clicked the download link and downladed a new file. It downloaded and installed with no problems (including accepting the key I was given). But now, when I try to open the application, the Xcelsius logo comes up, but then it immediately pops up a Windows message bos that says "Xcelsius has stopped working" and shuts down.
There are now two shortcuts and two folders for Xcelsius. I tried both the old and the new with the same result.
I am using Windows Vista Home Premium 64 bit. Can anybody help?
