loss of horizon and floating lights! HELP!

Hi all,

I just purchased P3D v2.5 with Rex4/softclouds as well as various other add-ons for p3d. My computer specs:

GTX970@4gb GPU

16gb ramp

i7 4970 processor

Windows 8.1.... and a bunch of other stuff. Its a home built thanks to Newegg.com.

My questions are this:

1) Unless I turn off REX, I have no horizon. Just a hazy blue everywhere. or, in otherwords. There are no distinctive horizons for cloud layers/ing... Part of me feels that my REX isn't actually working. Any suggestions on how to fix this horizon-less experience? Example: fog layers from 200AGL-2000AGL. There is no reason why at FL390 I have NO horizon.

2) no matter the scenery, I have floating lights for all airport surfaces.. Yes, I do have ORBX global installed.

Any solutions anyone can recommend to fix this lack of reality and get the true potential out of P3d?

BTW, I am very happy so far with the p3d program compared to FSX. Sure, rebuying stuff is obnoxious, but I'll get over it .

THANK YOU ALL!!!!
