Hog 4 PC V4.2.1.3764

Hi, hoping someone can help.

Have a Hoglet 4 and have been running Hog 4 PC V4.2.1.3764 perfectly fine, decided it did not want to work one day no matter what we tried (reinstall, reboot...). Eventually gave up and rolled back to V3.21.2. This version works perfectly fine, but we would ideally like V4.

V4 will install onto pc and start up, however only programming section of hoglet is talking to PC (no play back). When clicking into 'Control Panel', this causes software to crash when clicking either from show launch screen or once show has loaded.

Hopefully someone can help!!
