Reed Solomon Decoder Simulation - Missing Files?

I used the MegaFunction Wizard to build a Reed Solomon II Encoder and Decoder. The encoder works great; however, the decoder appears to be missing files. Has anyone come across this? The specific components that appear to be missing are:

In File: /rs_decoder_sim/altera_rs_ser_dec/altera_rs_ser_dec_0001.vhd

Components: DATA_FORMAT_ADAPTER_0001 and DATA_FORMAT_ADAPTER_0002 are missing

I am building for a Stratix V 5SGSMD5K2F40C2L

I am using the default options in the Wizard to build the design.

I am simulating with VCS.

Any thoughts or suggestions would be much appreciated.

Regards.

Andy
