Is it possible to copy one boot from winnin eleven and paste it onto a pes3 bmp.
I ask because i tried it and the game crashed right before a match

basically the boots look good on the edit mode but when i go to play a match the game fails to load whilst on the loading screen.
Any help?

They should work OK mate. As long as you didn't replace a PES3 boot bin with a WE7i boot bin it should be fine.
