Hello all,
when i try to reopen my saved project, blender returns an error “file format is not supported in file [+path]”
This is the second time it happens with this project. The first time I recovered a previously saved file and continued to redo ~4 working hours, in between I tried to open it again and it worked. But now the new file is corrupt again with the same error.
I really need to end this very work-intense project under these circumstances since there seems to be no other way out 
but I want to give it a chance by appending all objects and start with a new *.blend file. But at the moment Ii cant either open nor append from the corrupted file :spin:
Thanks all for your appreciated help!
Here is the latest file:
UH1D_V15.blend
