I have copied and pasted the license key provided by both web and email upon purchase on May 12. It works for only one day. Yesterday I was able to get it working again but not today. It fails with -2147418113 Automation error on Set objPort = New Port.
I originally wrote code with license key from earlier project then purchased new key. Old key does not work at all. Earlier project was successful. Both use XPembedded, VB6.
