Software inadvertently closes-out to desktop, then saved file won’t open, shows error message above when trying to reopen file, when file does open, it is blank. File looks intact in drop box and in FP desktop after you repeat import process. Other existing old files open and work fine, just last file worked on now locks up program. Memory has been checked, with multiple old files removed, but problem remains.

    After further attempts to recover work, it appears problem is with the floor level entries I used. Started with a generic footprint where I entered a 0’- 0” floor height. Copied that to make a 1st floor plan that I entered a 9’- 4” floor height. But, when I had already copied and modified the basement floor plan and went back and changed the default floor height to 0”, it crashed with that error message. I assume now means boundary where it says bound. Proved out by doing a much less detailed version where I did the same and it crashed, but then did one where I left the defaults the same and it doesn’t crash. Question now is, is there anyway to open the old file to change those values to recover access to all the original detailed work?

    Correction, it looks like I must have left the basic footprint I copied the others from at the default floor height and when the garage floor got reset to lower, which caused the error of “upper boundary is lower that lower boundary”?
