Dear Guenter,

Are you sure that the .spd file is intended to use with OpenVPN? I see the .spd extension in relation to SafeNet software, which is based on IPSec. OpenVPN is to my opinion really excellent VPN software, but incompatible with IPSec implementations, it should run in server mode on the other side too... If IPSec, you could try to configure racoon/setkey, which is far from easy. Better to consult the admin on the other end of the VPN first about the software which created your .spd file....
