my 108search assistant isn't workingg

hello. i was just wondering if ANYONE could help me.

i accidentally uninstallled my 108search assistant, so now when i look up some sites, the window automatically closes and tells me internet explorer is having a problem, and to restart it.

so i do, and then i have a pop up saying a third party member uninstalled my 108search and i have options, of course i pick to reinstall it..but it just won't work!

i don't know if i'm even in the right place to ask for help..but if anyone could..it would be very appreciative.

thank youu
