need help!

once i delete the script (just builded and empty ),crash! Y?

 

The only things i can think of is right click it & reimport it, the script may be open in another program, The script might be read only Right click on it show in explorer then right click on it again properties & uncheck read only even try deleting it from there, the other thing is you/unity doesn't have admin rights.

 

thanks,but,desn't work.. forget it，I will be carefully to build it..
