I've manually unpacked them, I've tried using both WinRAR and 7-zip. It didn't make a difference. The size of the folder 'Milfy_City_0.5pc' is 3.351.364.576 bytes, which is roughly 3,12 GB.
As far as I know, the only Codec I've installed is the K-lite one after a user suggested it to me. I tried Irfanview but it didn't seem to make any kind of difference. I had a version of Python installed on my pc, which I thought could be the culprit but even after uninstalling it, I got the same results. As a side note, I use chrome but I've also tried disabling all the plug-ins (extensions) and launching but to no avail. Adding to that, I do have VLC installed.
I think there might be an application or program interfering with the files or something not being read right.
I've got no clue what could be the reason and I'm starting to lose hope :l
Thank you so so much for trying to help me though, a lot of people scroll right by without giving it a second thought.
