Lost files in Trimble

I had about 6 or 7 files in the Trimble folder. 2 with Garden layout plans and 4 or 5 versions of kitchen unit layouts. Last acessed yesterday (9th Dec).
Today they all missing .Representing a months worth of my time and needed for discisions with a kitchen company on Monday!!! HELP please

Almost always when SketchUp Web users report their files are all missing, it’s turned out they’ve signed in with the wrong e-mail address. Make sure you are using the correct one.

I can hardly believe it, but I have just repeated attempts to access the files by exactly the same way as has been failing for the past hour … and bingo … the missing files have reappeared.
Don’t know whether to just be relieved or to remain annoyed at the grief I have just been through.

Saving the files onto my PC now !

Always a good idea to keep backup copies of any files.
