Tartop.Hi.
You Say,
"Show me where it says to install the java version I did, or where it says deleting registry files..."

The reason we recommend to use the most up to date java, is that hackers are
constantly finding vulnerabilities in java run-time which means, your java had
already been compromised ,causing corruption, that's why you had to reinstall.
Now!! that same vulnerability will be attacked again, thus You will need to get
JRE 6.
I would ask you to kindly refrain from telling people to alter there Registry in open forum, as most people are not able to safely make these changes.
I just wonder, how many have tried your suggestion, & Now need to reinstall
there operating system.
If you had posted your details in the first place with explanation of fault, Like we ask everywhere on these forums. I may have talked you through editing
Your registry in a private message. NOT ON OPEN FORUM. that's why you don't
see that fix everywhere. We like to help people here Not break their computers.
AND!! just to put the record straight, I have not given you personal instructions to do anything, anything you tried, was not personaly advised by me.
Peace.
