Ok well I just tried to recreate the problem with version 3.225.. and I no longer get the exception error
First, it was on TVShows, not movies.
HOWEVER, it seems that while I can browse for a local file and use it just fine.. I cannot download a file from TVDB
Click on Poster --> TVDB Specific
Select A Poster then click "Save Image" (either size)
After it attempts to download a popup error shows that says:
System.argumentException: The Path is not of a legal Form.
at system.io.path.normalizepathfast(String path, boolean fullcheck)
....<snip> lots of IO Path and Drawing locations
at Media_Companion.FOrm1.Button57_Click(Object Sender, EventArgs e)
One example of a show that caused this (Though I did try several) is
Doctor Who 2005, Trying to download the poster shown at: http://thetvdb.com/banners/posters/78804-18.jpg
I can download it manually and assign it however.
FANART works fine however as well.
Finally, the folder I'm saving to is a Network share.. However it is locally mapped to my "N" Drive. (N:\!Television\Doctor Who 2005\)
