1) Right now I'm stuck using version 1 because when I try to install the version 2 update, I get the message:

If anyone knows how to solve this, I would really apprieciate it. If not, I'll have to contact REX.
2) I've used some weather themes, but I'm having trouble using the flightplan function. I've read the manual, but I still can't figure it out after multiple attempts. Can someone please explain to me how to use the flight plan function with real world weather in the sim?
Thanks in advance.
