CUBASE 5, EXPORT VERY VERY SLOW (HOURS)

I have been using Cubase 5 le that came with my mixer for about 5 months now and have never had any issues. I record hip hop music and use very minimal VST’s…my mixes have always exported in about 2-3 mins. About a week ago I installed the waves 8 plugins and ever since then my mixes take about 1 hour - 2 hours to export…Even when I take all VST’s off and just try bouncing 2 tracks it would take about 45 mins…i have tried uninstalling the waves bundle and now still no matter what my exports are taking 1-2hrs

Not even concerned with keeping the waves plugins i just want my 2-3 minute export times back! Any ideas? i do not have the option in LE to “real time” bounce but i have clicked “update display” which i was assuming was the same option and it did nothing

[problem fixed] found a process running under “media diagnostic” on my machine that was taking up 90% of my CPU usage
