Unable to add or edit recurring calendar events. Error code:4000:C401?

This is the second time I've posted this question. On the he first submission I was asked for more info, which was supplied, but the question was never answered.

When I try to add or edit recurring calendar events, I get the following "It seems that we were not able to validate your login credentials . Please try again after logging out and logging back in again. Error code:4000:C401". I have logged off and back on, but still not able to add/edit calendar events.

Additional Details

This is happening on my desktop computer running Windows 7 Home Premium, Service Pack 1. I’ve tried it with Chrome 26.0.1410.64 and IE 8.0.7601.17514, resulting in the same error message.

I’m getting an error when I try to add an event or edit a recurring event.

Steps taken:

If a new event: Clicked New Event button, Entered information for the event, Clicked Save.

If an existing recurring event: Clicked the existing recurring event, Clicked Edit, Made changes, Clicked Save.

Error Message:

“We’re sorry! Something went wrong…

It seems that we were not able to validate your login credentials . Please try again after logging out and logging back in again. Error code:4000:C401”

I logged out and back into my Yahoo mailbox and got the same errors.

    I see this question was created 5 months ago and I just tried to save a new event (10/21/2013) and it still not working. I'm getting Error code:4000:C401 through Google Chrome. IE didn't give an error code, but it just didn't save anything at all.

    I basically created a clean team and am having a similar situation. Used 2 diverse computers and browsers, no substitute. i'm the mod and don't even see the upload adventure button on the calendar. the sole option below "strikes" in calendar is print.

    I am not getting an error code, but trying to post a new event in Our group calendar, and I continuously get the error message "Your access to this calendar is being processed. Please check back later."
