I don't know exactly how to access the log, but I'm trying. I can only launch the game from WinRAR as far as I know.

I think the log he is talking about would be the command prompt / terminal output that appears when the game is started. I agree with him that we do not know enough about your problem to offer any concrete advise.
It sounds to me like you managed to lose a portion of the files and folders that should be present in the Zip archive. I would suggest re-extracting the game into a folder by itself to ensure that you did not simply lose the Strive stuff in a clutter of other things.
For me on Windows 7 x64, Winrar offers an option in the right-click menu to "Extract to strive-for-power-win64-public\" which I use to automatically put everything in a new folder. With this in mind I'll give a basic layout of files for a Windows.
strive-for-power-win64-public\
Strive.exe
<15 other files>
.import\
<838 files>
files\
backgrounds\
buttons\
images\
music\
scripts\
sounds\
<32 files>
Edit: Actually, after thinking about it for a bit more, download and install a new version of Winrar. Not sure it's the problem, but if you haven't done that for a while, it may help.
