Because of the new WOT update, and everyone updating their modpack, the download speed of the "traditional" way has ofc plummeted. So For Everyone that has slow downloads : Download Aslain's DLC Folder instead, and select all files in the link and choose to download as a zip.
When you get the zip,uncompress it in a folder, and keep all the many compressed files there. Then make a folder in your WOT's installation ROOT folder,and name it, Aslains_DLC_cache_97 . (without the "." duh ... ) In THAT file cut (or copy) paste, all those small and big,many compressed files. THEN download Aslains Installer. When you run the installer then, it will NOT try to download anything, because all the files will already be there,and the installer will simply use them.
