[Modelsim AE]Fail to access fiftyfivenm_ver

Hi,

An error would be found and here is my step.

1. Run simulation with Modelsim ASE,no errors found.
2. Migrating from Modelsim ASE to Modelsim AE,run simulation.
3. The error message is listed.

** Error (suppressible): (vsim-19) Failed to access library 'fiftyfivenm_ver' at "fiftyfivenm_ver".

# No such file or directory. (errno = ENOENT)

Please let me know how to resolve this error.

Regards,

Jamie
