AMBER: unknown elements

Dear Amber users,
My proteins have three nonstandard residues. I made separate prep files for
them. There is no problems for XLEAP with AMBER7 on Linux and Unix machines.
However with AMBER8, XLEAP complains there are unknown elements on Linux
machines. And I found out that the unknown elements come form the
nonstandard residues. Anybody met this problem before? Any suggestions are
welcome. Thanks a lot in advance.
