Causing FSX to close when installed

[MikeS]

Hello. I just purchased the Accu-Feel form PC Aviatior and when I tried to install it it did a Direct X and failed then FSX will not open untill I uninstalled Accu-Feel.
Any idea what I can do?
Sorry but I am not real familiar with Direct X (or even what it is) workings and all but do know that I am afraid to mess up my FSX and would rather not try to reinstall the Accu-Feel without some guidance.
Thanks
