A file we have been working on since weeks, does not open anymore and shows the following error when opening it in Sketchup 2018 “Unexpected File format”.
We were working on that very file this morning without any issues.
All the .temp and .skb files dated from yesterday can not opened and show the same error.
This has never happened before and accounts for almost a full week of work lost.
Any wizards to help us out?
Many thanks in advance.
