BacktestTool - batch backtest, import and strategy parameters optimalization

[Stormrage]

I'm not a programer or script writer but got this error when running in console
Updating Gekko's bitfinex market data...
Done writing Bitfinex market data
Can't open $filename": No such file or directory
And this is from the where the error is.
P.S also running the binary gives me this

Failed to change directory to 'util/genMarketFiles': No such file or directory at script/backtest.pl line 489.
