Scribus 1.4.8 will not open any Scribus 1.4.7 files.
Displays:
"Fatal Error" "... is not an acceptable format"
"The file may be damaged or may have been produced in a later version of Scribus"
Sadly will be rolling back to 1.4.7 until fixed...
did you try 1.5.8? and is there a good reason to stay with the older version of Scribus?
