I only have updated from 5.1.5.0 to 5.2. OS is Windows 7 Ultimate x64. After updating I cannot use DownloadStudio to download from password protected websites. For example every try to download a video fails.

I don't know, what I have to configure within 5.2. I rolled back to 5.1.5.0 and everything runs fine.
