I'm old and need help with the dsetup.dll error

[StephenD]

I really am old, I'm 71. I have been gaming for at least 16 years and am not a noob.
Not being a noob doesn't mean I can remember how to fix things anymore tho.
I had this problem after the patch before but in my addled mental condition, I don't know what I did to fix it.
I have read threads here on the forum but can't make out what the instructions mean.
So, with that history, please be kind to grandpa and give me detailed instructions on how to get it going again.
Thanks.
BTW, I am the druid Barj that is so kind to port yur bum around so often. <wink>
