UI Mask Error!

I've been away from ReShade for a while, just recently returned and discovered that ReShade has a UI Mask, not exactly sure how I missed this before (prolly a combination of stupidity and laziness )

Anyways, when I try to use it, I get this error:

"ReShade/BasicFX/UIMask.h (48, 35): error X3011: value must be a literal expression"

I'm using ReShade 2.0.3.1120 on Warhammer Online: Age of Reckoning, got AMD CPU/GPU (7800 series GPU)

I've already searched for this on the forums and gotten mixed results at best, nothing that really addressed the problem.

Now yes I do understand that ReShade 2.x.x is not supported any longer, but I'm not sure if 3.0.3 has a UI Mask (at least I couldn't find it), besides, for some reason 3.x.x version of ReShade seems to be constantly loading effects every time one minimizes/maximizes full screen, which can take up to a minute or more to load, makes it quite inconvenient to do anything else while playing a game (not sure if this is by design, or maybe a setting that I've overlooked)

Anyways, any help on this matter would be greatly appreciated!

Thank You! (in advance) and please excuse any stupidity displayed on my part
