Runtime error 6025 when convert line to brush

I"ve been using 7.1 for a few months now. Recently I wanted to change lines on a drawing to brush strokes and discovered that whenever I press that button I immediately get a runtime error and the program crashes. I think there is a problem with the program that needs to be fixed right now!

What button are you pressing exactly? What’s your version of Windows or Mac?
Which specific model of graphic card is running on your system? How much video RAM is on this card?

In tools I was pressing the options to “convert line to brush”
I have a window 7 with 8 gig of memory and GForce 310M that has like half a gig of memory on it.

Well. Turning off of Areo on Windows seems to solve the problem for me know.
