Unable to run BaseCamp

I am unable to run BaseCamp.

I have three PCs with BC version 4.6.2 installed. Two are Windows 7 Pro - one for use at home and the other for when travelling.

I've just attempted to load BC on PC1. It errors with 'not registered |2633', which it can't report to Garmin. After switching off and on again, I get the same error.

On PC2, I get the same error.

Has Garmin disabled BC? So I turn off my internet connection and switch on my new PC3 which runs on Windows 10 Pro.

PC3 loads BC without any problems, so I turn on my internet and it still works. However, my database is on PCs 1 & 2.

Any suggestions as to why BC has been running in PCs 1 & 2 for a long time and now won't.
  • The CF-31 also now works.

    This poses the question: having provided a large amount of information including their error number and text, plus both .xml error files and all my feedback; why could a single person solve the problem, while the Garmin support department could provide no useful assistance?
