Selfcert no longer working correctly
 

I have used Selfcert successfuly for years. Recently it started asking
to 'Enable Macros each time it was opened. I went to VBA Tools -
Digital Signature - Choose and my signature when I chose it would
not stick. Then I removed it and tried to use Selfcert to get it working
again. Each time I get he message 'An error occurred during certificate
creation. Selfcert was unable to create your certificate.'. It does this
every time. I cannot find any reason for it, nor find any possible
solution.

TIA
