When you upgrade between number versions (e.g., from 5.3 to 5.4), you must regenerate your design libraries. This is not true for letter versions (e.g., 5.4a to 5.4d).
You can easily regenerate your design libraries with -refresh. You must use the vcom compiler with the -refresh option to update the VHDL design units in a library, and vlog with the -refresh option to update Verilog design units. By default, the work library is updated; use -work <library> to update a different library. For example, if you have a library named mylib that contains both VHDL and Verilog design units you would use both of these commands:
vcom -work mylib -refresh
vlog -work mylib -refresh
