I can't open EV Plugs

This is really weird. I can open the EVO plug-ins fine but for some reason I can't open EV plugs. When ever I try it says that it can't find my stuffit program. But I know that it works because it is working for my EVO plugs. Why is this happening?!?!? Someone please help!!!!!!!!! 😕

Er, what exactly do you mean?

The stuff-it program from alladin sw is what is used to open the plugs after you download them. It works fine for all of the EVO plugs that I get. But when I try to open the EV plugs, the computer can't find the stuff-it program.
