I have never had any problems on MWS.
If you have not been on in awhile, maybe you got knocked off. The FAQ section is not much help and contacts for logging-on help are non-existant it seems.
I sent a note , referencing your dilema, to Martin Quinn, one of the moderators over there. I will pass on anything I hear back.
A PM on the way to you.
I am a devoted follower of all of your work. Thanks for all your wonderful models and the info you've posted over the years.
