I have imported a personal certificate .p12 and when i press Select button in Digital Signing frame, it gives me this error:

Certificate Manager can't locate a valid certificate that can be used to digitally sign your messages with an address of <my_mail@mail_server.com>.

I have seen other people with this problem but none of their solutions worked.

you see other people with this problem? I don't normally. But I do have issues at the moment with certificates issues by Start.com. Who issued yours?
