I use virtuoso6.1.7. Just try a simple testbench tran using spectre.
simulation covers very fast 100%, but simulation pauses at writing information into some rawfile.
at this time, I can plot any voltage in the circuit, but I can't start a new test due to the above unfinished simulation.

You could try commenting out (or deleting) the info lines that request the subckt info. I don't use ADE, so I'm not sure where in the menus/dialogs you find the check-box to un-check to avoid this; I use Spectre at the command line so I can edit the netlist directly.

You should also check that you're not running out of disk space (though I would think Spectre would tell you if this were the problem).
