I have been experiencing the same problem intermittently. That is, when trying to access OLW, the page attempts to load about 8 times, and then returns the error noted earlier in the thread. I tried deleting temporary internet files and cookies and still get this error. Eventually, I am able to access my OLW pages. The thread does not say whether this issue was resolved.
I'm also disappointed when the slution calls for cookie to be deleted. Some cookies are created and used to save preferences (e.g. Google). Whe cleared, all of these settings have to be re-saved. It would be more helpful if a mask could be provided when asked to clear cookies, e.g. *microsoft*.
Thanks. Mark
