Ya I agree, good point, the OP's explanation even if you read it 3 times makes no logical sense. 
 
Especially this: And literally when I click the DL page for sonar on Firefox it doesnt open
 
If this is true then how would you get this: This program has got corrupted internal data
 
Your saying you can't open the Sonar download page, and then your saying you must have because you are trying to install the software???
