Hi Jack,
Thank you for sharing your question. Thanks for sharing your story. I get how annoying it is when a suggestion that's supposed to help just makes things worse, especially when you can't get to your stuff. If Clipchamp is stuck loading and won't take your password, it usually means there's something messed up with your account or how you log in. This can occur when you merge accounts or change your login settings.
Based on my knowledge Clipchamp needs your Microsoft account to know it's you. If you've mixed up or switched accounts, it might not know your login info.
Old login info or cookies saved in your browser can also cause that endless Loading Projects thing.
Here's how to fix it
If you're using Clipchamp in a browser, clear out your browser's cache and cookies. Then, try logging in again at clipchamp.com.
Double-check which Microsoft account your projects are linked to. If you put accounts together, Clipchamp might only show projects from the first account.
log in with the Microsoft account you use for your subscription or have used with Clipchamp before. Make sure you use the whole email address and the password you currently use.
Try using a private window or a different browser to make sure it's not just old login stuff messing things up.
I hope this answer is helpful, if you have any questions, feel free to reply.
Best Regards,
Noel
