You need to answer the questions we're asking. You don't go to the doctor and tell them "I hurt" and then expect them to know exactly where you hurt without telling them.
We need more information if we're going to hope to help you. There are so many possible causes of your problem that you need to help us help you if we're ever going to find out what's wrong.
Start by what operating system you're running and your system specs. Then tell us exactly what plugin you're trying to use. That way we can either try that plugin or if we already have it installed can say yes it works here or no it doesn't work here.
Just asking "now what should I do" is pointless.
