When I download the beta the zip file gives me this error message :
<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again. </div></BLOCKQUOTE>
I have downloaded the file multiple times on 2 different days with the same error message.
