Hi.
Sounds like some folder path in an variable are missing or wrong.
I tested it on two PCs, both with default Steam and SteamVR installation path without errors. Would be great if you can send me the content of your .log File located in HomeLoader\System\logs\ folder. Your config.ini File located in the System folder would also be helpful. You can open the log File by yourself and check it too. If you see any wrong or missing path then you can add it manually to the config.ini File. Will try to fix it and add it to the next update I am working on.

Here are both files: https://www99.zippyshare.com/v/RA8GFHFQ/file.html

Oddly enough though the log has nothing in it, just a blank document. So I have 3 hard drives and steam is in C while I downloaded homeloader to a different drive (D:) but looking at the config everything seems to be in order and it's got all the right places listed. Not sure what could be the issue or why it isn't outputting anything to the log. Hopefully you can figure it out though, I'm so eager to try it out!

I have released a new version, HomeLoader 0.77. Please try the new version. Before you run it for the first time please activate the debug mode in config.ini File for further investigation. Change the Value "Debug_Mode=false" to "true". It's at the beginning of the config.ini File at the fifth line. If you get the error again then backup all four log Files before you try to start HomeLoader again and send them to me.

Edit: Disregard, I'm an idiot and fail at github. Running it now. Also where do I unrar the place the dvd case files to? Looks like it's properly loading my games now, will let you know once it's done if I run into any issues!

~~~~~~~~~(IGNORE) On your github it says only 0.76 is avilable, and upon downloading says it it says it hasnt been modified since last month and in the config it says its 0.75 weirdly. Is here somewhere specialI need to update from? ~~~~~~~~~

Well it got a few hundred deep and then gave the error again, logs attached:
