Revit 7 conversion error

[Danny_Sim]

I have a 24 story Office block done in Revit 6.1 . when I tried to open it in Revit 7, i encounter this message.(Please refer to attach image.) Clicking either option, Revit will crash. or sometimes will bring me to another dialog box to save a recovery file. but when I try to open the recovery file, I'll get back to same error.
Thanks,
Danny_Sim

Sounds as though you should send this to Revit support to look at.
