The problem may be in the scale of FDI. Try to rescale it such that
the coefficient has a reasonable size (somewhere between 0.1 and 10).
So don't add FDI in euros or dollars, but in millions or trillions of
dollars (i.e. divide FDI in euros or dollars by a million or a
trillion).

Hope this helps,
Maarten
