Regarding the 737-700 Ultimate and it's download issues:
We tried to move the files to other storage solutions but the cost will ruin Threshold instantly.
So here is the solution:
When you get the quota message:
Too many users have viewed or downloaded this file recently. Please try accessing the file again later. If the file you are trying to access is particularly large or is shared with many people, it may take up to 24 hours to be able to view or download the file. If you still can't access a file after 24 hours, contact your domain administrator.
Right click the file and add it to your google drive. (you will have to have a google account)
Make a copy on your own G-Drive
After doing that you will be able to download it.
( if everyone donated 1USD we wouldn't have this problem. Or even better supported us to cover the ever growing forum and storage expenses with a 2$ subscription.. Just sayin )
