Error message is about email I used during installation. I'm not sure which email it would be. The only ones I would use would be dereklp4@gmail.com, buckeyelawnpros@gmail.com or info@buckeyelawnprosllc.com. How can I fix this?
The Support document regarding error code 24 is here. If that doesn't help try asking at Online Live Chat, advice here. (It seems to be available at the moment.)
