Go to airport...UATG and... crash !

Hello simmersI wanted today to check my next destination airport (UATG-Atyrau) by the command GoTo Airport (from a cold parking position), and, as soon as my airplane comes into view, it crashes or I get the message : "Too much pressure !".UATG is an unusual airport in the sense that its altitude is negative.Is that the reason for this bug ? I made some checks with AFCAD, and the runway altitude is -72 ft, but when I use a little program to correct the airport elevations (JABBgl) it shows an altitude of 4 294 945 m !? I corrected it to -21.9 m, but it did not solve my problem.How can I correct this ? Thanks for your ideas !Alain
