I have had a problem with the CMOS memory on my motherboard. To cut a long story short, I found that by removing the battery then booting up, reseting the BIOS and then replacing the battery I could remedy the problem (which was no display output). During the process I deactivated E6.5. Following the restoration of the memory I reactivated and all seemed well, but subsequently I had to go through the whole process again, but this time I had not deactivated E6.5. Now I am asked to repeat the activation process, but this results in 'The serial number is not valid' response. E6.5 has only been used on this computer.
Can someone kindly advise how to proceed.
