My computer wont let me play runescape...because of the high detail updates. it just shows a box with an x at the top left hand corner. what do i do p.s. how do i level up easily?

Java

You do not need to play on high detail. You can choose low detail which is still the old runescape requirements. If the box is still like that, it means you have no Java. So install the latest Java from

www.Java.com.

Leveling Up;

Depending on your level you could train at gorillas in the monkey temple on ape atoll. You could also train at the bandit camp in the desert.
