It takes FOREVER to download purchased content using the Reallusion Content Downloader on a my Mac! (I have OS10.14)

Does any one else have trouble downloading content?  My internet speed is not great as I'm in a rural area and have satellite access only but I don't have a problem with other internet downloads.

I have installed the latest Reallusion Content Downloader and updated the Hub and CrazyTalkAnimator 3.3 and have followed all FAQ and tech support instructions/suggestions for downloading content I bought last month. It would download a tiny bit then hang not even allowing me to cancel. Each time I would have to wait for 4 or 5 min for it to time out and say "Network disconnected. Download failed." before I could click the retry button again. Many times it wouldn't advance at all. It took 2 days before I was able to complete that download!

Yesterday I purchased additional content and once again it is hanging and I'm having to wait 4 or 5 minutes. I keep getting "Network disconnected. Download failed." I tried all day yesterday and again this morning and have managed to get it to about 2/3rds downloaded so far before it wouldn't advance at all. I've even tried cancelling (which I can only do when the retry button comes up) but that takes me back to the start! I will persevere this time but PLEASE offer an alternative. Zipped file? Dropbox?

Very frustrating. I've looked at all the help pages, FAQs etc. What can I do? Please offer another way. Is this happening to other Mac users?
