Having file issues

[raymondmill]

Hello,
I'm a returning player after some time away (last patch I used was v39), and I'm having trouble updating my spell list. I have the latest patch, v55, and have attempted two fresh installs. The issue seems to be with the dsetup.dll file. When I replace it with the v55 version, the game won't even start. However, using the v39 dsetup.dll allows me to reach the character screen, but then I get a "spell files outdated" message. The only file from the latest patch I'm missing is the dsetup.dll.

I'm playing on a 2012 iMac using Wineskin and have had no issues with this setup in the past.

Does anyone have any suggestions for resolving this issue?
