Revit 8.1 to 8.0 file conversion

[m_cahoon14336]

I have a Revit 8.1 file I need to convert back to Revit 8.0. I know this has been discussed here before, but I can not seam to locate the thread. Any help with this conversion would be appreciated.

Yep....There are valid reasons for it too.....(However, yes, in an ideal world it would be nice)
....this is the last thread on the subject, but there were earlier ones.
