Materials are missing, all the models are black

[pebble]

Hello everyone,

Recently I saved a file as archive from a computer whom corona license has been expired. I opened the file on the other computer whom corona license is active but its saying that files are missing and the models are black. I tried to convert the scene to corona renderer, I relinked all the missing textures but its showing the same thing.
What should I do?

Can you please clarify on which corona version the archive was saved, and is it opened on the same version? 

Lastly, was the scene converted using 3dsMax's Scene Converter with Corona Preset?
