Trimble Business Center

I have lost several days (and several nights) of sorting region cleanup work. All points of various classes have disappeared.
I have been working without problems and saving the file regularly, however, the last time I closed the program and answered "yes" to save changes, a message popped up saying "the *.vce file could not be found"
Before clicking accept I verified that the vce file did of course exist and was in the correct folder. So I clicked accept and the program closed with apparent normality. When the project was reopened, many of the classes were empty.
I have been able to restore all the missing points by invoking all the "unused points" in the default class. But they are all undifferentiated within this class and I have to start classifying again. Has it happened to anyone?
Regards

Trimble business center, I lost my classified ground region. I opened a new drawing dragged and dropped the jlx file. classified the point cloud then turned everything off but ground region selected the ground and under home tab export file format point cloud las exporter then dragged and dropped the las into the Trimble file I was working on and then I had my ground region back. Maybe drag all back in and it may bring back your classified poles etc?
