Just bought a month subscription to try it out and everything looks pretty good with the exception of getting fatal error when closing P3D. Happens everytime! Anyone with fix for this or where I should check??regards,Well after checking event log shows API.dll the problem. So anyone know how to fix this dll??

That is a known problem with version 1.2 and LM will fix it in the next release (don't know when that will be). Just click cancel and it will return to windows.

In my case this 'fatal error' was caused by FSUIPC. After I removed the module all was fine again.Harry

The P3D shutdown problem is caused by Simmconnect and its compability, or current lack of it. FSUIPC uses simmconnect, hence the hiccup at shutdown. Any module using Simmconnect will produce the same problem.

Arnie....if it ain't broke, don't fix it...
