Maybe somebody has some insight on this, but today I went to launch Reason and I got the following error, "Can not open Reason Engine. Please reinstall to make sure that the Reason engine is properly installed."

So, I reinstalled Reason, but I continue to get the same error.

i'm also working with a macbook, but i have never eoncountered this problem. have you had any success since this first post?

Could anyone refer me to a good zune forum or something? I'm really desperate. (thats why im posting
here lol)

Yeah, I ended up downloading the update from Reason and then changing some settings in the Preferences menu to accomodate the problem. It turns out that there was some sort of issue with the ReWire settings... Let me see if I can find the fix and i'll repost it.
