If anyone could help me resolve this issue it would be greatly appreciated.

**** Running the ModelSim simulation ****

C:/altera/13.1/modelsim_ase/win32aloem//vsim -c -do 64bit_counter.do

Reading C:/altera/13.1/modelsim_ase/tcl/vsim/pref.tcl

# 10.1d

# do 64bit_counter.do

    I suspect you're not quitting out of your sim before you re-run it - if 'work' already exists. Do you issue a 'quit -sim' command anywhere before running, or re-running, your script?

    Cheers,

    Found the error actually. Altera did not like the leading number in the project name.
