i found out that you can use texture packs in the minecraft pcgamer demo and i was wondering how to install them. (also please post some texture packs compatible with the pcgamer demo) and to those who are like BUY THE GAME!!!!!!!!!! my computer wont run the minecraft game but it will run the pcgamer demo.
If you do have the actual game I advise you follow these steps. Also how doesn't the game not "work"? Please explain. Does it lag? It doesn't start up? It crashes while playing?
Update your Java.

Do Windows Update.
Post your dxdiag if the previous steps don't work.
