I need help... PLEASE

Hey, guys my Zorin os 9 is a bit messed up. Every time I turn it back on tends to be more and more random errors popping up. I don't know how to upgrade to Zorin 10. I don't know how to download anything unless it's through wine or playonlinux and even then it's confusing. I can't download Runescape, teamspeak 3, or anything else. Whatever it is turns into folders or pointless junk and I'm never able to do anything! Errrg...

Listen, I know I'm just ignorant here but I'm asking... Someone PLEASE teach me what I need to do!

Runescape has an unofficial Linux Version (Is what I use)
https://github.com/HikariKnight/rsu-client/
https://github.com/HikariKnight/rsu-client/releases/tag/v4.3.3

Teamspeak also has a linux version.

After you download the ".run" files you will need to run the following.

Code:

cd Downloads
chmod 755 ./*.run
ls | grep .run
./filename.run


you will need to replace "filename" with the name of the file.
