If it's 5 years ago you probably went to the old SATS lounge, the one near the cinema and outdoor smoking area/cactus garden ?. The new/current one is near the SKL's, opposite the MH lounge, and is waaay better than the old place.

If you are going to any lounge at KUL, I would strongly recommend you check out the new Rimbun lounge. If you are checking in at KUL you'll pass it after immigration and the first security check. It's to the left up the escalators.

It's much better than the satellite lounge and is usually very quiet. I've been in there a dozen times in the last few months and there has never been more than half a dozen people in there. If he's working the Indian gentleman (in the first pic on that link above) may sulk a bit if your flight is going from the satellite terminal. Just tell him you prefer the Rimbun and want to use that instead.
