BB Bold 9700 :: Desktop Manager / Device Password

I have a Blackberry 9700 phone which has been working fine up until today when I decided to load the "Blackberry User Tools" software onto my P.C. at home. After successful installation and machine restart, I was asked to enter my "Device Password". Assuming this would be my password I set originally to lock my phone I entered it and found this didn't work. I subsequently attempted a number of other logical permutations but then realised that if I continued I would lock my phone. So I stopped (at 8/10 tries) and called my service provider "Orange UK" who advised they couldn't help me and that if I continued to enter the incorrect code, it would wipe my phone as it would automatically reset!When I connected via USB last time, it asked for me to enter the word "blackberry" which I did but when it then asked me to enter my password (which I assumed was the four digit numerical code I had originally set the phone with) it failed to work. I am now left with two further attempts. Please can anyone assist by advising me what I can do to overcome the problem without wiping my phone as the contents are very important to me.
