Fail on upload: 'program.tool' not found

Hi folks,

after renew my win7, the Arduino Ide 1.5.7 make problems. I tried burn my program via Diamex-AVR stick, but now an error message comes: 'program.tool' not found. My entry for this programmer stick inside 'programmers.txt' was : diamexavr.communication=serial diamexavr.protocol=stk500v2

after this error message I added a line, now I have diamexavr.communication=serial diamexavr.program.tool=avrdude diamexavr.protocol=stk500v2

But the error message is the same (I didn't forget restart the Ide)

I need help, I can't imagine what's happen..
