This is has been an issue in the past, especially with a 302 and using
SeeYou.
Best not to use SeeYou. This has been a long standing
bug in the Cambridge/SeeYou/OLC interface. Use only the Cambridge
utility, 3UTIQ257 if using an IPAQ product, or 3UTPC256 if using a
laptop,
to download the file from the 302 to your computer or IPAQ. Then you
may
upload the file to the OLC web site using the direct claim method.
Seems to
eliminate all the invalid file problems by removing SeeYou from the
process.
