Ive got a new monitor scince the last time i used sensation(it was a while ago back when it was on AAL) i have other clients that i can use but i would like to just try sensation again and be able to use the first ever client i bought

When you go to the page it should show you how.

sorry i dont understand what you mean and where i should be looking

A monitor is not going to affect you're hwid. You would have had to have changed something else for that to occur.
