MT4 Strategy Tester returns blank for Results, Graph and Report tabs

Hey Guys,
I’m new to the Strategy Tester in MT4. The other day I tried to do some back testing using a couple of simple EAs and some indicators but I get no results for the Results tab, Graph and Report Tabs - they’re just blank.
The Journal tab didn’t show many errors but it showed the results; how many bars it processed, how long it took, how many wins, how many loses, etc.

I followed a tutorial from this forum on how to run a back test in MT4 but there’s nothing in the tutorial on trouble shooting.

I’ve even uninstalled MT4 (latest version) many times and re installed but the same result. I’ve tried different simple indicators but made no different.

I searched on google but found nothing.

Any idea why I’m getting blank pages for the Results, Graph and Report tabs?

Could the MT4 experts, please point me in the right direction?

Any assistance would be greatly appreciated.

Cheers
