Having trouble with authentication

[NermNermNerm]

I had been using this up until a couple weeks ago, where I ran into problems with authentication. I tried updating to the latest version and still no luck. Perhaps you can tell me how I'm holding it wrong...

1. Start fiddler
2. Open nexusmods.com in a browser, verify that I'm logged in
3. Scrape the cookie out of the request headers
4. $env:UNEX_SESSION_COOKIE="%7B%22mechanism...-bS%22%7D"

I get:

PS E:\repos\NermNermNerm.Junimatic> unex check
| WARN|: Cookie validation failed!
PS E:\repos\NermNermNerm.Junimatic> get-command unex

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Application     unex.exe                                           3.0.7.0    C:\Users\sbenz\.dotnet\tools\unex.exe

I tried it with ```$env:UNEX_SESSION_COOKIE="sid_develop=%7B%22mechanism..." as well, but no luck there either.
