FxSound started having problems

For the last few days, FxSound stopped opening normally, and, when used right after turning my PC on, it made my speakers screech loudly.

Also, it only opens once then refuses to open again even when running as administrator, and the equalizer stops working.

Is there any way to fix this?

Ah! That sounds annoying… Could you try uninstalling and reinstalling if you haven’t already? Download FxSound - Boost Your Sound On Windows

Are there any other new applications you’ve installed or any other changes you’ve made to your PC since this started happening?

Thanks for your kind answer.
I uninstalled and reinstalled the app several times, and no, I did not install any other app since it happened: I just updated FxSound to its latest version.
After the update, it started malfunctioning.

If you need further info or want to share more info with me, you can reply to this post, thanks.

Ok gotcha. Can you try uninstalling and reinstalling an older version?
