Sorry to be the bearer of bad news but no one from MSMW staff have responded to this forum or email contacts for over a year. Don't ask me why they disappeared though...I don't know...I am just another MSMW client like you waiting for MSMW to respond.
Regarding downloading themes...
I couldn't wait forever for MSMW to get back in the game since I am a Managed WordPress Cloud supplier who needs to support clients on the defunct MSMW themes so I created a community fork of the open source MSMW themes at https://backstopthemes.com and upgraded the code to support php7 and WordPress 4.7 (I'm bringing the jquery up-to-date next). For the techies, you can participate in the community at https://gitlab.com/BackStopThemes.
NOTE: This excludes Awake and inFocus since these are proprietary ThemeForest distributed themes.
BackStop Themes instructions:
Note: Always make a backup of your current system before upgrading your theme in case you want to roll back.
Manual upgrade options are:
a) Copy the new folder contents into the old folder; OR;
b) Rename the old folder, upload the new folder; OR;
c) Delete the old folder, upload the new folder
I tend to use option b.
Remember to download a copy of the old theme folder first as a backup. If you upgrade using option b or c you will need to copy your skin folder and css file from the backup theme copy folder to the new live theme folder.
FYI - BackStop themes is a community-based support environment for the now defunct MSMW themes. Please keep in mind that support is now community based so please be patient. None of the money you spend / have spent on MySiteMyWay goes to the new community-based support environment which was established and is maintained by OnePressTech Pty Ltd.
If you choose to continue with BackStop Themes you can email email@example.com to be added to the BackStop Themes newsletter....welcome to the new community :-)
