Garry's Mod Server - Can't change active gamemode - 'darkrp' not found.

I have been getting this error for quite a while now, and I am getting sick of it. I have followed these 2 tutorials: and - followed them 100%.
My start.bat has this line: start /wait srcds.exe -console -game garrysmod +gamemode darkrp +map gm_construct +maxplayers 16 and it is correct too. But then, when I run my server, it says in the CMD “Can’t change current gamemode - ‘darkrp’ not found”. It is all up to date, and I have put the darkrp folder, in the gamemodes folder, with the exact same name - tried reinstalling everything too but still gets this, and it really pisses me now :pwn:

I run Windows 8.1

Any help will be much appreciated!

If you look in your gamemodes folder and see a folder called “DarkRP” rename it to “darkrp” because the gamemode bit in srcds start up line is case sensitive.
