问题
We just purchased a performance license, when adding it to the config section, and running /resizer.debug we get the following error:
resizer configuration(Warning): License key was issued in the future; check system clock: ourdomain
License keys You do not have any license keys installed.
System time is fine. Perhaps the generation of license key is in US timezone? We just have to wait?

Waiting a few hours rectified the issue.
