Hello,
First of all I would like to say it is awesome that KSP now has a mod manger (been away for a year or two). However, I have a problem with downloading mods from Curse using your program. For an example I tried to download KSA using the following URLs:
[url]http://kerbal.curseforge.com/projects/kerbal-attachment-system-kas[/url]
[url]http://kerbal.curseforge.com/projects/kerbal-attachment-system-kas/files/latest[/url]
[url]http://kerbal.curseforge.com/projects/kerbal-attachment-system-kas/files/2266204[/url]
Everytime I entered the URL and hit add mod, it would connect online for a few seconds and nothing would happen, no warning, no error and no mod.
However, I am able to download these mods manually via the browser and KMA2 is able to handle mods from KerbalStuff fine.
Cheers,
