Hi all,ref the 3.08 exe error mesage,( using XP ). I initially got this while following the instruction to copy it to the airnav folder & overwrite the 3.07 exe,could not understand why programme opened still showing v3.07 not 3.08.Removed the 3.07 exe from the folder leaving the new 3.08 exe in its place,tried openning the programme using the desktop short cut,got message saying searching for exe,then realised that it was the v3.07 shortcut looking for the 3.08 exe,so created a new shortcut for the new 3.08 exe,put that on the desktop now works ok,have also restored the 3.07 exe to its original place in the same folder as the new 3.08 exe & that also works from its 3.07 short cut.I got fooled as only used to running the full installers before, first time I have just downloaded and installed just the exe file.Hope this may help someone else.Regards Paul.
