Fastrack Supreme Infinite loop

I download a .dwl file into my Fastrack Supreme and it is in an infinite loop. It does not accept any AT command. So i cannot download anything into it or query the Fastrack Supreme. I have looked at some posts and it seems to erase the program from the memory of the FAstrack Supreme i have to use DWLwin. I don’t have it, neither in the Open AT installation CD nor can i find it on the wavecom website. Please can someone tell me how i can get it. If possible attach the .exe file
