Hello, I ran into a problem where I can't upload my item using Workshop Upload Tool. After I hit the Upload button, it instantly crashes, saying "SDKFrontend has stopped working". I tried checking the game/sdk cache, tried installing the game/sdk to the default steam installation folder, tried choosing the file as a upk/zip from the game package folder/unpublished folder/any other location, checked if the sdk process isn't working at the same time. It even crashes if I simply hit the Upload button without actually choosing the file and preview image. My OS if Windows 8.1. I also tried it from another PC running on Windows 7 and got the very same issue. I spent too much time working on my Guns 'n Gear contest entry and I don't want it go to waste. How can my issue be resolved? Has anyone had the same problem?
