So far smooth as silk.
Installed original CD, went right to the 1.1 upgrade, then did the seasons add-on, then ran lomac.
The activation popped up, I put in my key, it did it's check and said I had 4 activations left, then lomac came up just fine.
Frame rate is about the same, I noticed that flares are very effective at spoofing heaters...
Ok, back in for more configuring and flying...thanks ED...nice.
