Im having this same problem. I have included a zip of my CMS folder in my post here https://www.reallusion.com/FeedBackTracker/Issue/Reallusion-Hub-wont-open-at-all
Hi davidharrington1991 Thank for your reply, I will check your post there! Tina
I've reinstalled it and it fixed it, but after 2 package installations, it began happening again. I had to shutdown iclone and reopen it, and it began working again. I believe there is a bug that causes it to lose sync or something.
Hi Yossi Did this issue happen again? Feel free to let me know if any! Thank you Tina
Hi Yossi This is a complicate situation and it also randomly shows in our end. So we need you to help us clarify the root cause. Please go to path C:\ProgramData\Reallusion and you will find a folder named "CMS", "Copy" this folder and paste it to other path, then zip the folder, upload the zipped file to cloud, provide download link to us, we can identify some necessary info, you can set your next post as private if you want. And could you please try to uninstall the installed pack, and install it again, check if same message popup again? This may be also a condition to help us find the question. Thanks for your help Tina
try to uninstall and reinstall the Smart gallery plug-in in HUB. hope it will help
