Cubase 6.0.5 stops working when importing a track archive

Sometimes when trying to import in Cubase 6.0.5 a Track Archive created in an earlier version (Cubase SX3 or Cubase 6.0.2) the program stops working. The same goes for Song files created in those earlier versions. No problem with files created in version 6.0.5.

After some testing I’ve found that the problem is caused by one or several tracks with plugin automation. Eliminating this automation the problem disappears. However to eliminate the automation I need to open previously the Track Archive or the Song file. With files created in Cubase SX3 I have no problem because I have it installed on an old computer so I can open the file and eliminate the automation. Not so with Cubase 6 previous files that can’t be opened in SX3 or 6.0.5.

Any ideas?

Any help?
