re 1: first time this keygen hasn't worked for me.
re 2: OK, yeah, I've been using the 2010 keygen and it totally sailed past me that this was a 2009 app.
re 3: Yes, but since the generated code would not copy/paste, I chose "Type in..." and the spaces provided are more than the character count of the generated code.
re 4: me => XP SP3 32 bit.
In the end, I found a working version that replaces the exe. One thing I've wondered is if this type of solution is considered as proper as the keygen type of crack.
