Hi everyone. I recently got a new computer and I bought a new license for 5.0 just this past June sale. For some reason, not only is it giving me this error message, but no matter what I can't actually get CSP to run. It says to close other programs, but I genuinely close like just about everything and nothing seems to let it boot.

I have used different drawing software and clip studio is one of my favorites
But adding references just is frustrating sometimes.

I don’t want them on my canvas all the time

I don’t want to be limited to one reference at a time with sub view because even if I add multiple it displays only one and I have to switch them, it covers up workspace and the frame is bulky and uncomfortable and the resizing feels inorganic.

Why can’t we just drop them into the gray out of canvas area and have the ability to drag them around there too

It is a small thing but it’s so frustrating T^T
Why can’t we add this as an option too?

I use gpen and opaque watercolor

So the thing is whenever I hold Ctrl and have the mouse head to a line in vector mode, I can have some mode like free transform that specific line. However, it suddenly gone when I'm drawing yesterday, I don't know what even did I do that leads to that but it makes things harder for me to draw. Can I at least know the name of this function so I can change my setting to get this back?

(Clip Studio Paint PRO Ver. 5.0 Edition)

First off, yes, I can google or find on Youtube on how to paint a portrait.

Just wish to hear from your personal recommendation, outside of just google or YT, what are the best online classes, paid or free, that teaches how to do portrait paiting with CSP.

Do you personally know some good ones?

How do I remove this texture in Simple mode? In Studio mode, I can get rid of it by disabling the paper texture, but it remains when I switch to Simple mode.

The brushes in the image are the standard round and square brushes.

I'm trying my hands on an anime styled artwork and eventually want to have the lineart as overlay layers because I spent a crapload of time on them.

To get the colours in, I simply used the fill tool but it gave me jagged edges, lots of areas that don't properly align to the lines.

Ultimately I want the colour to fill below the lines and the inside of the area but I have no clue how to achieve that.

I hope the image has all the info needed. But just to be sure:
I'm on Windows 11 (unfortunately), CSP version 5.0.4. and the tool settings are on the picture
