the problem of "updata" in sopc7.1

Hello,

When I open a .ptf (sopc) which was built in quartus 5.0, there is a problem that

Error: sram1: The component sram_256x16bit_classic 1.0 could not be located. Add component paths to the Global User Libraries in Quartus II.

Many component have these problem except for sram1.

how can I solve this problem .

thanks in advance
