It's only the tilde ~ key on US configured keyboards, but wherever you are (hmmm let me take a guess on that based on your username!) it is the key immediately to the left of the 1 key and above the TAB key. In the UK this is the ` key (the ~ key for us is way over the other side of the keyboard and does not open the console)
Edit to add: if that doesn't work, try opening the .ini file and finding the line that activates the console, bAllowConsole, if that line has a value of =0, change it to =1 and save the file. MAKE A BACKUP COPY of the original ini file first though just in case it messes anything up and you have to restore the original unamended file.
