JD,Must the 3.01 update be installed first before the 3.1 build or can the 3.1 be installed over 3.0 directly? I've decided to do a reinstall to try and solve the saved flight lockup problem. The 3.1 install did not help. Thanks.

you should be able to install 3.0 or 3.01 from cd (whichever is on your cd), and then update with all the 3.1 files (don't forget the 11.zip, 12.zip and wavupdate files)jd
