According to the information on their website, the software benefits from free support. If the application freezes for no apparent reason, then you can try a few things:
The obvious reinstallation of the software. If there is a corrupted file or registry, reinstallation will fix it.
Software configuration. It's possible the software is bugged and it's causing errors when a certain option is used.
Conflict with other software. While the software is running, close all the other ones.
