Trust Mouse not working anymore

NVM I'M AN IDIOT, I REPLACED THE BATTERIES AND IT WORKED PROPERLY AGAIN.

My mouse stopped working after I installed Steam.
When I removed Steam, it still didn't work.
I really don't know how to fix it.Oh and I can't turn it off now unless I remove the batteries.
Forgot something again... When I insert the batteries in the mouse it'll start working again for a few seconds.Can someone help me?
