autocad error

Does anyone know why autocad creates this error? Recovering does not help at all…all info is completely lost. Plus…for some reason autocad produced no temp saves…they all have 0 bit of info!

do u have it while u use orbit command?
if yes select 3d in (from autocad 2007) as working area and not 2d and it should solve.

hope it helps

I was not doing anything. Last night I saved and closed with no problems. This morning I opened the file and there was this error…now the file no longer opens. The backup file does not open either.
