Nostalrius Begins - Quality wow vanilla realm (1.12)

Can someone help out with this? I installed SweetFX, however every time I start the client I get the following error:



It pops up around 7-8 times, but when the game finally starts the effects work. Suggestions?

Hey did you managed to fix this error? As I think I have the same, even tho I can see the pic.

i have the same issue, but it works fine after clicking past the errors

I have this problem but I have been using SweetFX for a long time and the errors only started showing up recently, maybe since patch 1.8. I have thought it was one of my addons.
