Dell was able to fix my certificate error by resetting Internet Explorer http//support.mircosoft.com/kb/923737 and then delete temporary folder by going to start, run, type temp,ok, select all files by hitting Ctrl and letter A, Press Shift and delete together. Then go to start again, run, type Prefetch, ok, select all files by pressing Ctrl and letter a together. Press shift and delete key together, click yes. Hope it works.
