Hello,

I've just updated through FTX Central  Open LC Europe for (according to the site) a minor update...as a result Prepar3d v4 does not start any more? Any idea on how to sort this?

Many thanks for your help

Do you get a crash when clicking OK on the scenario load screen (before any progress bar comes up)?

If so, you could be having this issue:

LM are aware of it and hopefully working on a fix.
