Hello, for some reason i cant get any plugins to work. Im using firefox if it helps, when i download it the only options for me are, Ok or cancel, and when i click ok it downloads then a new screen pops up and i ave a few more options, open or cancel, i click open and a new page on the internet pops up and nothing's on it, Can some one explain in detail on how to get it to work?

.

Well if you're talking about HMT v3.5, then there's a folder in there called 'plugins' this is the folder where you need to paste the plugins you have downloaded, restart HMT and they will be visible.

Thanks got them working
