Error generating New Contact List?

[ka9qjt]

Greetings, I was using the latest (5.0405.1) editor to adjust some channels on my GD-88 today. I thought I'd take the opportunity to write a fresh set of contacts as well. When I selected Generate New Contact List, I was greeted with an Unhandled Exception error message. See the attachment. I tried a few things, including uninstalling and reinstalling the software, rebooting, etc. No luck. Anyone else bumped into this? I recall that it worked in the past.

Thanks and 73,
