Cannot simulate TSE - Design unit not found

Hello,

I am trying to simulate my module from sopc using the triple speed ethernet ip.when I try to simulate I get the error

"altera_tse_mac.v(376): Instantiation of 'altera_tse_top_gen_host' failed. The design unit was not found.# Region: /macb/b2v_inst/the_triple_speed_ethernet_0/altera_tse_mac_inst

"

So i grabbed altera_tse_top_gen_host.v from the library and added to working directory and tried to compile... then i get this error

Error: altera_tse_top_gen_host.v(

syntax error, unexpected non-printable character 0x8b

Error: altera_tse_top_gen_host.v(

syntax error, unexpected $undefined, expecting "class"

So I open up the file altera_tse_top_gen_host.v in notepad++ to see why its not reading the model and its....gibberish? Full of weird characters. Is this a fault in the altera library? Or is the v file meant to look like that.

Thanks
