I get a blank screen page displayed instead of the home page when clicking the Quality center hyperlink.This happens after navigating between two different instances of QC. I tried deleting the loader class files and the mercury interactive folder. Then restared the system. Still i am unable to access the QC page of one of the instances, but the other instance displays the QC page.

Does it have anything to do with the space available?
Please let me know a solution at the earliest.
