Temple of Elemental Evil & Wineskin/Crossover Games

So, I'm running TOEE via Crossover Games. I got the game from GoG and patched it with the Co8 mod pack. I'm getting a fairly well known glitch, with flames, lights and spell effects flickering or becoming entirely invisible.

I've looked around and it seems there are some fixes, but most are when using Wine, rather than Crossover Games. I'm told there was a wrapper created here http://portingteam.com/files/file/60...lemental-evil/ that fixes this problem. I'm told you can put your existing game files in this wrapper and it will fix the glitch. The problem is, I can't seem to figure out how to do this.

What I've done, is go into Crossover and accessed the wrapper I made in Crossover, by going to Configure - Manage Bottles - Picking the Wrapper I had made to run the game in crossover - Advanced - Open C: Drive - ???

Now, from the C: Drive, I've tried several things. I've taken the TOEE folder and dragged it into the wrapper downloaded here http://portingteam.com/files/file/60...lemental-evil/ and I've traded files back and forth, I've tried everything I can think of. The app from the new wrapper will look like it's going to start when I double click it, but nothing ends up happening.

What am I doing wrong? I'm told I should be able to fix my game and keep its progress by just using this new wrapper. Anyone know what I need to do?

 

To thicken the plot, I've now just started to get game crashes when trying to go from the 2nd floor to the first, via a stairway. I get a message saying the game encountered an error and needs to close. It talk about compatibility with Wine, but I can't copy the crash log, because I have to hard reboot.
