I think Rick initially thought you had posted a license key here, not a trial ID. That’s happened before and it would let others take your license key, so we try to make sure people know not to.
If you’re using a machine that doesn’t have working end stops you’ll need to use ‘Current Position’ as the ‘Start From’ mode, and set the Job Origin setting appropriately. Read about how that mode works here:
For the trial extension, when you have the machine back up and running, just send an extension request email with the trial ID to email@example.com and we’ll take care of it.
