MusescoreGeneral.sf3 doesn't work properly

Hello,

I am using musescore 3 and have been writing some orchestral notes for some time and was using musescore's standard soundfont. I wanted to change it to have a better and more realistic sounds and uploaded a virtual orchestra soundfont. I used it for awhile but i didn't like it and deleted it to get the standard soundfonts back. But when i deleted it, standard soundfonts didn't come back, instead of that i got different and volumless sounds in the program. The orchestra sounds like a quartet now. I want to get the standard version back but i don't how to fix it. I would be so happy if someone help me, thank you.
