Thanks goes to all who are up for a challenge,
I have a AutoCAD file... please bare with me here... originally created in 2008, converted to 2004 and now can not be opened in 2008.
The acad.err file says:
INTERNAL ERROR: !dbobji.cpp@6769: eNotOpenForWrite. I have no idea what is causing this. The file was created in 2008 Land Desktop Companion and has point objects called "AECC_POINT"s. Other than that the files are pretty clean.
Upward and Downward compatibility has never been AutoCAD's strong point, but hopefully there is something I can do to make the process a bit less painful.
Thanks for the Help, Mike
