1. Uninstall Java
2. Go to oracle website archives, download JRE 6u45 ( if it asks you to make a java account - A quick Throw away with false info should work )
3. Install Java from the exe you just downloaded.
4. Go to C:\Users\<ur name here> & Rename Salem to something like Salem-old-noender
5. Restart Computer
