Please just open the weatherFX app, when you notice such bugs. It has an error report. It seems you miss the shader patch update. Sol 1.1 beta 6 requires Shader Patch preview 46 or later. So just follow these steps:
First: delete dwrite.dll in AC root folder!
Download latest Shader Patch
https://trello.com/c/TIWtynNR/59-v0125-preview49
Drag'n'drop it to CM -> Open menu (symbol becomes green) -> press install
Download latest Sol beta

Drag'n'drop it to CM -> Open menu (symbol becomes green) -> press install(edited)
Can I use these steps updating from shader patch v0.1.24 and GBW or would I need to delete the shader patch
thanks
