I am encountering a problem while trying to upload a map of mine. Cooking it works perfectly fine, though there is no way for me to select a preview image since whenever I click on browse to search a picture it just switches between the cooking window without opening another instance of some sort of an explorer window as it used to do. I have already uninstalled the entire dev kit and reinstalled it afterwards and yet I am still encountering the same problem.
It would be awesome if anyone knew where the issue is and had an idea on how to fix it.
Thank you in advance.
