BEWARE: DO NOT purchase any product from Chronosnet.com if you expect a response to purchase/serial number problems or bug resolution requests.
Too bad, since many of their products are pretty good: I own SOHO Business Card, SOHO Labels and, now, Labelist, an upgrade to SOHO Labels. I purchased the upgrade May 5, 2012.
When the purchase receipt email arrived it had the serial number and so forth.
But the serial number did not work. And their only response, elicited via their clumsy ticket system on their website was: "Well, it worked for us."
I couldn't respond to their email since they won't accept emails. So back to the ticket system..And since their ticket system does not, apparently, allow for attachments, like a screen shot of the input serial number box and the failure message that came up next, I included a Dropbox link of a zip file of the screen captures.
And I never received any response even though I filled a a new ticket several times.
