Problem with EURUSD data

 
My EURUSD is wierd in that on my 5 min graph the candles go back to 15-12-2010 with 5 min candles. Then from there I get day (24hr) candles. Does anybody know where the EURUSD data is stored in Metatrader so that I can re-download it. My indicator won't work until I fix this...
