X-Lander Barometer off

[ramtwin]

Please excuse if this topic has been dealt with before, I just could'n find an answer to my problem in the posted threads.
My X-Lander barometer seems to have gone crazy. It reads all sorts of numbers (negative), which keep changing all the time. Have tried resetting to factory default settings following the instruction manual without results. Altimeter/Thermometer mode are equally off. Can anyone help? Thank you.
