sse optimized audio dsp library message at load of cubase 5

Running Cubase 5…when starting program the splash screen stops at “SSE optimized audio DSP library” and will not start program. I looked around on the internet and found info saying that it might be Qucik Time giving me this problem…uninstalled Quick Time with no success. Any help would be great thanks!

And your system is what…? :unamused:
