IF you did a complete uninstall (manually deleted al the folders left over) and then reinstalled and got crashes with a totally vanilla setup, then it may be something with your software or hardware. however, if you didnt (EDIT: go through and delete left over folders/traces) it seems that you didnt install the proper skeleton.nif required to run Dual Wielding Redux and it is still present in your vanilla game. this may be the cause of your crashes, however, i cannot be certain as I do not have dual wielding redux, but I have read the full read me.
