I've recently been having issues with Google Chrome downloading WADs from the idgames archive. At first, it was telling me the download was insecure and now it won't download anything at all. I'm still able to download through Firefox and both are on the latest version. It seems like possibly something in the https cert is messed up, but I'm not a web developer so I'm not entirely certain. Hope this can be easily fixed and it's not super widespread.
