reactivate expired trial for Designer with v1.2 rather than the old v1.1
I recently saw on the Sencha site that trials of the previous version of Designer would (could?) be reactivated now that Ext4 support is available.
I just downloaded and installed Ext Designer 1.2.0 and received the "Unfortunately your trial has expired" pop-up when trying to run it (/opt/ExtDesigner-1.2.0/ExtDesigner). I also downloaded/installed the latest ext-4.0.2a-gpl.zip in readiness to trial.
How would I go about such Designer reactivation?
