@phaolo, I live.... again! ;)

Some game files had web encoding strings in their names ("%20" for space for example). So I added an "unquote(item.name)" somewhere. As I said I did not try the last version. Maybe it's an old problem and you have fixed this meanwhile. I just wanted to let you know.

BTW: A nice and sunny Easter for everyone!

Edit:
Tried the script meanwhile - problem still exists. See mini-dump:
"...1x shadow_warrior_2/patch_shadow_warrior_2_1.1.11.1_%2813954%29_to_1.1.13.0_%2817267%29.exe"
When adding "unquote(item.name)" it looks like
"...1x shadow_warrior_2/patch_shadow_warrior_2_1.1.11.1_(13954)_to_1.1.13.0_(17267).exe"

Edit 2:
It seems to be a naming problem at GOG: I have noticed that some files are okay even if they have parentheses. For example...
"...1x kingdom_come_deliverance/setup_kingdom_come_deliverance_1.8.2-247j_(27382)-7.bin"
So some names at the server seems to have web encoding strings and some do not. Anyway an unquote can normalize this.

Welcome back, but.. what happened!? (if I may ask).
We tried contacting you in any way, even on Steam.
You disappeared before an announced new gogrepo release and didn't say anything, not even a goodbye\farewell. O_o

The games were hidden. Thanks for asking :) I have no issues to report at the moment, but it took some learning Linux and sudo apt commands to get comfortable with Python and try again this last time. Obviously, I got it working :)

Thank you for this project!

Strange, I have that game and mine downloaded as: patch_shadow_warrior_2_1.1.11.1_(13954)_to_1.1.13.0_(17267).exe

No files in my collection have %'s in them

What OS and version of Python are you using?

Okay. So it does not depend on GOG.

I use(d) Linux with Python 2.7.6 (standard/default).
