Just tried starting PSXT (after MSFS 2024 was started and all set up at the gate) and I got a "reading airports failed!" error message as can be seen here:

https://ibb.co/fdhK2x69

I've been using PSXT for two years and never had this problem and haven't made any changes since I last used it.

Can anyone help?

Many thanks,

Ben

It failed to read airport.enc.

Just try again.

I've tried a number of times now and have the same issue. Here's the log:
