Good afternoon Graham,
My apologies for your trouble on behalf of the team.
I’ll tag and PM FxSound’s lead audio engineer @bvijay to ask for his advice.
Not to offend, but many people use the new version of FxSound without problems, so my guess would probably gravitate more toward some sort of system or device incompatibility.
Either way, this is a link to free downloads of previous versions, in case the incompatibility is version-specific.
And this is a quick link to my standard troubleshooting list.
I hope your problem can be resolved, but if not, there are other audio enhancers available online:
- Chrome EQ extension - free
- FireFox EQ extension - free
- DeskFX - free
- Neutron - paid
EDIT:
