I was having this exact problem for a while and didn't know what to do. I finally found a way to fix it.
- Install LAV Filters (like it says in the op)
- Right click on the startup icon, go to properties, click the compatibility tab, and check the box to have it run in compatibility mode Windows XP (SP3)
- Run it using AppLocale as administrator
Worked for me, not sure if it does for everyone.
