Hi All,
my plugin uses an URL object to check for the product authorization, it does a POST call from prepareToPlay() method.
The plugin runs very well on Logic, Cubase and other hosts. Though on Vienna Ensemble Pro 5 it crashes.
Here’s the crash log; it seems that the issue is related to JuceURLConnectionMessageThread.
Any ideas?
Emanuele
