Hoping that a solution can be provided. I have been working on a huge project on Photoshop Touch on Android tablet, have invested over 40 hours. Have regularly saved project. Have just gone to open project and getting 'cannot open as it is not a valid project' I can still see the project, but cannot access it , or copy picture to camera roll, or save to Cloud. Is there anyway I can access the file within android to recover file. It would be dreadful if I have lost all my work, I need to be able to use a reliable editor with no risk of corruption. Look forward to comments.
Could you please give some information about the size of the project.
Image size and amount of layers?
Is the thumbnail still showing the content of the file or is it gray/black?
Did you ever switch application during saving?
Looks like I'm not the only one having this issue. I've lost two projects with many hours invested in each. Same thing, thumbnail shows everything. I can download as a psd onto my desktop, but half the layers are empty.
