Yes, there is a problem with the hwbot certificate on your system. It has a fairly new root or intermediate certificate from their certificate provider, iirc.
Normally this happens if the bench os has not been updated in a long time, or hasn't had an internet connection in a while. Many certificates in the Windows certificate store won't be valid anymore and that breaks the certificate chains. The easiest way is to update.
I tried to solve it in the manual BenchMate installation but failed to fix it. I will try again soon.
Easiest way to fix this is to install updates.
