Thanks for the reply!
I have this problem with every image I try to edit, not a specifc one.
Consider the Platform 3 (UI).capx, from the folder examples (from the examples included in the construct2).
If I try to paint the blue square (player) red then the this error message pop up and the Player sprite will disapear.
Well, i don't think that it's a bug in c2, because i just try that, and the blue square is painted red succesfully. So it maybe a problem on your side, try to update your graphics card driver to a latest version, update construct 2 to a latest stable version r173, if you had latest drivers and construct 2, then try to reinstall c2. Oh yeah and launch c2 only as administrator and save and open your files only from directories that has no access limits (like desktop). I hope something can help.
