Frequently Asked Question
Why am I getting an ECAM message 'ADR 1+2 FAULT' when I load either FSX Real time weather or ASN (and baro pressure changed by 2 or more mb's).

This is not a bug and is real A320 behavior. Per the ESLD - "if barometric conditions change more than 2mb from pre-engine start to after, you need to go back and power down." Once the aircraft gets into FWC phase 3 everything will be OK.
