Can't upload clips to Vimeo

I have been using Premiere Elements 11 to directly upload videos to vimeo for over 3 years with no problem.  Now suddenly this week, I keep getting the same problem as described above. I m prompted to Authorize Elements to upload to my Vimeo account. I then click Authorize, and a browser opens for me to log into Vimeo. When I do so, and click Allow to let Elements upload to my Vimeo account, the browser then goes to a blank page. In Elements, there is then a dialog box with a button that says Complete Authorization. When I do this, I receive an Error and am told "Your authentication details could not be verified. Kindly try again." I've tried this repeatedly to no avail. I have existed the program. Turned off and on the computer, and even used a different computer.  Still won't work.  Has Adobe made a change that prevents Premiere Elements 11 from uploading directly to Vimeo?

I tried the work around saving it as a .avi, .mpeg, .wmv, then upload to Vimeo, and it says the file is too large.  Same length videos I have been uploading weekly for over 3 years directly from Premiere Elements 11. Any help would be appreciated.

There are too many changing variables between Premiere Elements and Vimeo or YouTube requirements.  That said sometimes it works.

A sure way to get videos to YouTube and Vimeo is to do it in two steps.  First, output a high quality video that will play well on your computer.  Then, second, use the Vimeo or YouTube uploader to put your video on line.
