Import Export error...need help (newbie)

I'm a web developer and use oracle for sqlplus commands.  However, the need has arisen for me to import data set up on a different system.  Basically, the following is happening:

imp dbuser/pass@db file=thexport.dmp

yields:
IMP-00010: not a valid export file, header failed verification
IMP-00021: operating system error - error code (dec 2, hex 0x2)
IMP-00000: Import terminated unsuccessfully

Checking the versions of both, at the top of the .dmp file I see:
^C^CgEXPORT:V08.01.06F

and when I start the import I see:
Import: Release 8.0.5.1.0

Is this simply a version conflict?  We have an oracle 9i db running, but maybe the import/export wasn't upgraded in the process?

when you exp/imp the database, you DO need to watch for the imp/exp tool version compatibility.

the simple rule of thumb when you do exp/imp from the different version of databases,
you should always use the LOWER version of tool to do the IMP/EXP.

There is also another possibility.  If the version was incorrect, then it would be likely that this would be the error.  Did you ftp the file over to the other system as ascii or binary.  It should have been binary.  Oracle will bark if it was not the right type.
