Jaime,

I have tried the following with limited sucess.  Cd to the directory and 
mv key savkey
mv data savdata
cp savkey key
cp savdata data

By moving you are able to keep the data on the same part of the hard 
drive.  Copying back makes a copy of the file to another part of the hard 
drive that might not be bad.  If the copy is sucessful then chown the two 
new files to filepro and try and go into IUA.  If you still et the segment 
lenth error - try adding one record in expand records.
