I'm getting an error saying

"Market does not accept apks signed with the debug certificate. Create a new certificate that is valid for at least 50 years.
Market requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate."

Can someone give me some easy steps to doing thing? I just cant figure it out!

I guess you haven't changed the keystore? You can't as it says use a debug kestore for publishing. I don't remember exactly how you make one tough, but some time ago i made one using the command prompt.

The code should look something like this:

1

$ keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
