No .sopcinfo file from Nios II IDE

I use the DM9000A Ethernet Controller from Terasic Technologies in the SOPC Builder. After upgrade and regenearte it, I get following Error message from the Analysis & Synthesis from Quartus II:

Error: Port "iRST_N" does not exist in macrofunction "the_DM9000A"

This is the function:

DM9000A the_DM9000A

(

.ENET_CLK (ENET_CLK_from_the_DM9000A),

.ENET_CMD (ENET_CMD_from_the_DM9000A),

.ENET_CS_N (ENET_CS_N_from_the_DM9000A),

.ENET_DATA (ENET_DATA_to_and_from_the_DM9000A),

.ENET_INT (ENET_INT_to_the_DM9000A),

.ENET_RD_N (ENET_RD_N_from_the_DM9000A),

.ENET_RST_N (ENET_RST_N_from_the_DM9000A),

.ENET_WR_N (ENET_WR_N_from_the_DM9000A),

.iCLK (clk),

.iCMD (DM9000A_avalon_slave_0_address),

.iCS_N (DM9000A_avalon_slave_0_chipselect_n),

.iDATA (DM9000A_avalon_slave_0_writedata),

.iOSC_50 (iOSC_50_to_the_DM9000A),

.iRD_N (DM9000A_avalon_slave_0_read_n),

.iRST_N (DM9000A_avalon_slave_0_reset_n),

.iWR_N (DM9000A_avalon_slave_0_write_n),

.oDATA (DM9000A_avalon_slave_0_readdata),

.oINT (DM9000A_avalon_slave_0_irq)

);

In SOPC Builder, I'm not able the edit the model of DM9000A because it can't open the model anymore.
