I betcha it's because there are 2 vendors that co-created that product. Ran into same issue, so just emptied cart.

Today was the official release of DAZ Studio 4.12. A lot of us think something overloaded the servers or the DAZ site connection to CloudFlare related to that. I can get to the forums now and FINALLY got DIM to connect but downloading products is still kind of slow and iffy.

Today I made my first order in a couple weeks and had no problems at all downloading my files. So whatever it was seems to be no longer happening. (Maybe it was some kind of CDN-type issue like DAZ is having today; after they had a site problem today it seems to be taking forever for things to get back to normal as stuff propagates back out over CloudFlare.)

I wonder if is partially the traffic load at different times of day? Sometimes if I start before dawn Eastern US time (not an optimal solution as I work 2nd shift and get home after midnight) I can get some files successfully downloaded for a couple of hours, but not always. For instance today I had 5 failures in a row of one file I was trying to get. Later in the day I experienced a first: almost instantaneous downloads. It was so fast there was no time for the progress to stall and fail.

I really don't care about the download speed so much as repeatedly getting to 80 or 90% of a file downloaded then it fails, so it's start all over again... and again.. and again.

Anyway I am finally caught up with the dozens of files in my backlog stretching back almost 2 weeks at one point.
