PT 11.3.0 Video Engine not launching

Hello,



All of a sudden the video engine hangs on initialisation, I can't get it to launch at all.



Have tried reinstall, deleting prefs etc, repairing permissions etc..



To no luck.



I'm in the middle of a Video Post job currently, so this is very annoying.



I have searched around for answers, there are people with the same issue but none have given a resolution.



If anyone has experienced this please let me know,



Thanks for your time,



T.
