Being a bit hard on the OP IMO.
Vr 9 still can't process more than 3 files on any windows machine I own without throwing up the "error when processing a file". Phase One used to bring out solid code, with few bugs, but that seems not to be the case. Vr 8 for months had the issue where on minimizing to the task bar, then later bring C1 to the forefront again, C1 froze. This issue was fixed later on in a later version of C18, but it took several months.
Issue of 'error processing a file" has been taken forward multiple times to P1 and the only answer so far is totally disable open CL, which is not a great answer.
Vr 8 never has had this problem and there are times when I need to run a large batch job, I will drop back to Vr 8, (as it's not that old, just one release back) and it has most of the features that Vr 9 has that I need.
