FFScroll Uninstall? WIFI not on Menu?

[Mastermind278]

Hi everyone. I just installed Jas 10.4.8 on my Acer 5102 and got almost everything to work. I was trying to figure out the touchpad so I could scroll and decided to install the FFScrollPS2-0.1.RC1. However it was very unstable and just not working good with my touchpad. I tried to figure out how to uninstall it, however I did not figure that out. So I tried to delete the files that got installed, however now I lost access to the touchpad, nor does my keyboard work. Will I have to reinstall OSx to get it working again? If not what are my options?

 

Also another issue I have is that when the computer boots up to the OS it will not load the WIFI automatically. I have to go to System Preferences, and Network then to Airport to get it working. Though I click show up on Menu, after a reboot it does not.

 

Hopefully you guys can help me with these issues, and hopefully will not need to reinstall everything all over again. But if I have to I will just do it. Thanks!
