I also checked my F and it was indeed an F and the H was correct also. I suspect ruthie is right in her surmise that you have saved over. I have done the same thing before. I'm so sorry, I'll go vote for the F for you. Good Luck! ;)
I've just checked mine, maxken, and the 'F' is definitely an 'F'. If you haven't already done so, check all the letters to see if it turns up under another name. The only possible explanation I can think of as to how your problem happened is that if you downloaded 'H' to the same folder that you saved 'F' into, you might have accidently clicked on the 'F' filename and saved the 'H' as that name. In which case you've overwritten the 'F' file with the 'H'. If this is so, all you can do is hope the 'F' is given as a freebie another time, or take out a 6 month membership. I've sent you a flower, hope you find the 'F'.
