Thanks for your very quick reply Alexey.
Using the File Menu -> Cloud -> Download Project option I am able to see all the projects I have on the cloud. However, when I start to download I get the same error message:
"CloudManager: Can't check synchroniszation (project name mismatch)"
So, I tried a different project, also using File Menu -> Cloud -> Download Project , and that seems to be downloading fine. So could this be a corrupt psx file? If it is just a corruption in the naming can I fix this somehow?
To be honest, I cold start this project again from the beginning, as I have only aligned images and built a preliminary cloud. However, woudl be good to understand in case it happens again.
Thanks
Tom
