Force to move to windows 7 and fsx and I need help with the Cessna citation x 2.0

I cant get the I.R.S to align on the Cessna Citation X in Microsoft FSX even when I push the test button. the align light just starts blinking. I couldn't find any help on the Eaglesoft forums. has anybody else had this problem? Thanks. p.s. Everything else works fine.

Make sure ground power or the apu is hooked in... the IRS won't align using just the battery.

Thanks DJ I'll give that a try.

Nope didn't work with ether GPU or APU engaged. I'm at my wits end here. Thanks anyway DJ.
