+(Regarding crash reports)
+If your new to this you can find your crash reports in "<minecraft directory>/crash-reports/crash-<date and time of crash>.txt"
+If there are multiple just select the latest one. 
+It may also help if you include the latest client log which will be located at "<minecraft directory>/logs/latest.log"

+Instead use a paste service to such as pastebin.com (Or what ever you prefer)
+
+If you have never used pastebin before its pretty simple and does not require an account or anything.
+Just go to pastebin.com,
+Copy the *entire* contents of the crash report into the "New Paste" text box  
+Then press "Create New Paste", This will create and open a new paste in your browser.
+Now simply copy the URL from your browser and paste it into this issue.
