Invalid license key
I'm getting an 'Invalid license key' error.
Evaluation versions of PingPlotter Standard, Pro and MultiPing all have licensing encouragement after a period of time. This reminder usually has two buttons - 'Enter License' (or Register), and 'Do it later'. The 'Do it later' button is disabled for a period of a few seconds. The 'Do it later' button will eventually enabled itself (after a few seconds), so just wait for it to un-gray, then hit that button.
You can, of course, purchase a license at any time to stop the reminders. After 30 days if you want to continue using the software, you do need to buy a license. If you have a license key that doesn't seem to work, try copying it from the email from us, then pasting it into the software. Also, make sure the license you're using is for that editions of the software - PingPlotter Standard licenses won't work with PingPlotter Pro or MultiPing.

Please include your old email address - or any additional information we can use to track down your original purchase.
