Need a little help please

[Neptune#1]

when I try to use some of the different ships I have downloaded loads ok till I get the message to please wait then it just sits there, I have to use control/alt delete to get out then I get a message box :data/menu/gui/recmanual/couflaguuw.dds I looked in the SH4 files and rec manual is there, is this because the new ships are not in the original rec manual? and how can I fix this thank you.
