Up to recently I have been able to play Minecraft but suddenly I have been getting the black screen and Minecraft wont load. I know that most of you will say it's because I installed a mod incorrectely but I have not because I have deleted the file in the minecraft.jar and also have completed deleted the .minecraft folder and re-installed Minecraft, I have also re-installed Java but still nothing.

When I was able to play Minecraft before it kept giving me an error after about 10-30 minutes of playing that Minecraft had run out of memory I know the cause because when ever I run Minecraft from the client Java never opens but when I launch Minecraft from the browser Java does open, I am not sure if it has something to do with Firewall because whenever I start the Minecraft client it gives me a message saying are you sure you want to run this program.

If someone would please respond and give me an answer I would be very thankful.
