New in Forum and bug report

I used for a long time BFD3 but not the forum. From some days, I have regularly crashes with Reaper with the last BFD3 version. It becomes impossible to use it. Everytime BFD creates a “bugreport” file but I don’t know what I have to do with ! Please where is any clear explanation what we have to do to send a bug report on the forum or on another place … And if you have simultaneously an explanation about this great bug… i will be enjoyed ! Thank you
