Rebuild history cache?

 
Hello,

Is there a way to rebuild the history cache?

My M15 EURUSD is missing data from March to June - just doesn't display on the chart. Can MT4 be tricked into rebuilding this without re-installing?

Thanks for any help/advise.

I tried that, didn't work. Is there something else?
Thank you,
