after about 20 seconds after starting battery and standby power and external power the EFIS EICAS and IRS are running then they just simply shut off, whats up with this. i have reinstalled my fs before but it didnt do this before.

hmmm how long is it going to take for you to reply , PMDG.i have re installed my fs many time before and all other a/c work fine except yours.

If you're exhibiting such impatience, why don't you send an email to our support@ hotline?Provide your order ID number, and details, so you will be helped promptly.

That would be because you do not have a properly registered product.Also - if you want PMDG support, instead of posting here, I suggest you consider sending mail to the official support address.- Bill
