[SOLVED] Lag when loading a track

Hello, I dowloaded the Rekordbox trial a while ago but when I'm loading tracks on a certain deck it lags for about 20 seconds. The screen freezes but the sound keeps playing. I also get software an unexpected application error sometimes when it's playing. This all is a bit annoying so is it my laptop or the software? Because if it is the software it will be a dealbreaker.

Rekordbox version 4.4.0

System specs:

Microsoft Windows 10 Home Version 10.0.15063 Build 15063

Intel(R) Core(TM) i3-2350M CPU @ 2.30GHz, 2300 MHz, 2 core('s), 4 processors

4 GB RAM

Thanks.
