Hi all, have anyone come accross the below problem ?
YES with Smath 5346 that has the "File rcovery" as well as your latest version.
It happened once to me and nothing could be done, not even from backup. This
same problem was encountered in Mathcad 11. Don't trust me, but a lost file
is lost for ever. Most probably from unknown bug in the "memory Checksum" at
the time of saving. Differently than Smath/Mathcad, OriginLab backup works
fine and no file can ever be lost, working in background.
Good luck, let us know.
