Having trouble scrolling back on MT4 H1 chart

I’m trying to backtest a strategy on the H1 timeframe. However, MT4 will not let me scroll back past the 3rd of June 2014. I’ve disabled autoscroll and also tried enabling chart shift but to no avail. This problem is affecting all pairs that I’m trying to demo trade. I know I have the data as I can view it in a higher time frame. How can I fix this problem?

Thanks

I’ve solved the problem by going to the history centre and downloading data for the pair. Just another MT4 quirk I suppose.
