plug-in messed up widget functionality

I've asked for a refund but was told it was not possible until you've addressed the problem and tried to fix it, which I am open to, but don't have lots of time to get this to work. I'm hoping it's an easy fix.

After I installed the plug-in per instructions, my entire widget page ceased to function -- I couldn't grab and move anything into the sidebars as I could before installation. I'm using Weaver II for this site (Wordpress).

Once I disabled the plug-in everything worked normally again. Please advise -- thanks so much, Leslie Riggins
