Brush limit Illustrtor?

[#1]

I'm just curious is there a limit to the number of brushes you can have loaded? Or a folder limit?

I brought a large pack of brushes to help with my designs, but I can not load them all. They work fine separately but when I try to load a chunk of them it doesn't work. I've tried all at once, sections of them at a time, even singly. 

When it reaches a certain point it can no longer load any illustrator file. And I have to go back and delete the brushes. Not to mention I have to close and reload Illustrator every time I want to see if removing or adding a brush has changed something.

What exactly are your troubles about?

Loading man brushes libraries and using some of the brushes in your file?

Trying out a lot of brushes in your file and then deleting the brushstrokes if you don't like the brush?

Having a lot of brushstrokes in your artwork?

What kind of brushes are they? The watercolor kind? Detailed pencil strokes? intricate patterns?

No, I literally copy brushes over to folder of brushes as I've been told to do in tutorials. But it literally makes it so I can not load illustrator at all. An error comes up (shown below)

Exactly what do you copy where?

And when does this pop up?

What makes you think it's related to your brushes?

And what kind of brushes are they?

So I start off by going to the below location

Then I copy the files on the right, to the folder on the left. 

The brushes then work fine. So I close illustrator.

And when I open up illustrator to use again, I get the fault which appears on the loading screen before the app has launched completely.

If I then remove the brushes I can load Illustrator normally. I just find it weird that if I did any of these brush folders singularly it works fine. It is just when I add too many of them it does this.

As for what kind of brush they are, I'm unsure what you mean. The file type is .ai or if you mean more the style they are all sort, scatter, pattern, calligraphy, brush stokes (sorry unfamiliar with this terminology) .
