Using Ypops/Windows 0.9.6 Alpha 1 (that has sure been out a long time now, without any update to Beta, nor Alpha 2, nor even Alpha 1.01

). Windows XPSP3, with Outlook 2003.
For years Ypops has worked for me well, no problems.
Some months ago, I was unable to receive Yahoo e-mail through Outlook-Ypops any more. My settings had not changed, but I could not receive any mail. I would not get any error message--Outlook would just report no new messages, yet if I looked at Yahoo web mail, I would see new messages. I was using Ypops 0.9.5 at the time.
So, I installed this Alpha, hoping that would solve the problem. It didn't. Exact same problem.
Then I saw the suggestion here to switch to the New Yahoo Webmail, instead of Classic. I did so, and voila, it worked, I could now receive Yahoo mail through Ypops-Outlook again.
Today, however it does not work again. When I try to receive Yahoo messages via Ypops, I get the following error message:
YPOPS! Yahoo Error
Yahoo API reported the following error:
mod_yahoo_auth:Expired credentials
(Note -this error message box was apparently generated by Ypops itself.)
I click Close on the box, then receive an Outlook box telling me server 127.0.0.1 (as it's always been set up), and listing my user name and password. I click OK, then it starts trying to receive again, and I get the Ypops API error again as above. Next time I actually retype my password in the box, when that box comes up, same error.
Yet if I go to Yahoo on the web, there is no problem signing in with my user name and password. (But that "New Yahoo Mail" is a pain--so slow!)
What is going on? What is that Ypops API error all about? How can I fix this?
And--when will the beta come out? Or Ypopls 0.9.6 Alpha 1.01?
I'll post just the log from my most recent attempt tonight. (I don't think you would want the whole log, 38+kb, goes back to 2005!) There is also an error page created, called yahooerror.html. Should I upload that also? (Just looked at it though, including view source. Nothing there, other than the Ypops error message I already received.) (And tried to upload, and was told "extension .html not allowed".)
Also, I see an .html file in my Ypops folder from the same session, entitled ListMessages_Inbox.html. I open that, and see a similar error message, although not worded exactly the same:
--Request: date down Inbox remove-javascript Response: SOAP-ENV:Client.ExpiredCredentialsmod_yahoo_auth: Expired credentials.---
Well, here is the recent section of the log:
