Hello everyone

!!!
I'm new to FS Dream Team scenery...so far i like what i see in the screenshots...i'm actually downloading the demo version of O'Hare as I type this

. I just have some general questions...
Why is FSX Service Pack 2 required to run this scenery???
My AI traffic program is World of AI (I love it!!)--can i still use it with this scenery???
Will your detailed, true-to-life scenery kill my frame rates???--I get about 8-12 w/ 100% traffic...kind of depends on how my computer is feeling that day

...
How much does the full version cost (it's listed in Euros but dollars is the currency here in Iowa)??
My laptop is pretty capable of handling complex loads...i'm curious to see how well this works
Thanks for your answers!!!
