Tested a little more tonight, EHRD also below sea level... One thing I didn't mention was I was using REX weather
normal flight CTD
changed ldg alt to -50 incase it just didn't like 0 CTD
installed ASN 7day trial CTD
May try another flight tomorrow if I can think of another option, any suggestions?
The weather radar for Ifly and ASN, works so this would lead me to think the 737 is installed ok, in the fs2crew folder there are the 2coupons that came with the update so I would also assume that installed ok....
