I am not sure what your problem is exactly. Is it with GetMod failing to download the vmod or GetMod failing to download missing components? From your screenshot it looks like your problems are related to getting missing components. rF2 only supports so many redirects. I am not sure if your use of sn.im will work. Have you considered just using my GetMod service to register your components? It is WAY easier to deal with because you end up with a common URL for all your components and then on my site you dictate the download URL for the component. You can even have multiple URLs so you can host your components in several locations and it will randomly rotate the URLs so you distribute the load.
There isn't a lot of documentation. I need to write up some new documentation one of these days. For now the best thread to read is this one:

I am also working on a tool that will list all your installed packages and give you the ability to automatically repack a component with your own URL and then if you want you can click a button to register the cmp on my service and when clicking that it will prompt you for the download URL you want to use. Right now it is a pain to use my service because you have to cut and paste the cmp name, then cut and paste the sig, then cut and paste the download URLs. It is a lot of cutting and pasting if you're registering 10 components at once. It will be nice to cut this process down to a single click and then a single paste for the URL. I hope to have this finished today.
