It all started when I tried running Minecraft which I found when I was strolling through youtube, but at the loading, Java crashes and gives me no error message. When I retry, theres an error saying:
An error occurred while loading the applet
Please contact support to resolve this issue.
Fatal error occurred (5): null
I started googling for a way to fix this, but I just found threads made by developers with this error, it wasn't really helping me, the user. Then I found it, the result that eventually led me here. It was a log of the IRC channel #lwjgl, with Notch, the maker of Minecraft, asking for help with this error. I googled lwjgl, found this site, tried to play some of the games listed in the projects page, none of the games that I downloaded worked (when Minecraft starts it downloads lwjgl files). I've also tried Wurm Online (also downloads files to the computer), which instantly crashes when I click on Play.
When I tried running Lavirinto 3D, JRE was kind enough to add a log file which I've attached to this post.
