The program was working fine for the first week or so. Now I frequently get the message, \"info: your serial number is not valid\" and the entire chessbase program just shuts down.\" At least it asks me if I want to save before it shuts down.
I'm hoping I get a similar remedy. Thing is, this problem is with the chessbase application on my computer rather than with playchess.com, and I haven't found any way to enter a serial number in the chessbase application itself. If I had a way, I'd re-enter my serial number to see if that helps.
Anyone know a way to enter the serial number in the chessbase 9 application itself I know in chessbase light demo, you are asked for an SN every time you try to do something, because it's just the demo until you buy a license. But in CB 9, I've never seen a way to enter the SN.
If a serial number is not already present in the text boxes type the number that you received with the program. The serial number can be used to install the program on a maximum of three computers. If you want to install the program on a new computer, or you want to re-install your operating system, you should first deactivate the current registration online. 153554b96e
