hi Shift_E,
just ran into this runtime error 430 when trying to fire up QMT, I'm running the current v 1.8.8 and also have VAC v1.6.7 which is registered and running fine.
I tried to un-instal/re-install QMT as per the other thread on this topic, but no go.
I havn't tried this with VAC just yet...I'd hate to lose both, just in case
all the best
