I give up.
I've been trying to install a plugin called 'Circular text'. I tried following the 'HOW TO INSTALL PLUGINS' thread. First with the free version, then with the paid version. The problem is I can't find 'Paint.net' on my pc. I've also tried tried to create the maps I'm supposed to in 'Documents'. I tried inserting the dll file in my newly created 'Effects' map and also the 'File Types' as one forum thread recommended.
The 'read me' file attached to the plugin tells me to download 'OptionBasedLibrary v0.7.9.dll' and 'OptionBasedLibrary v0.7.9.dlc files'. I found the files on Dropbox and have them now. They're old though, from 2015 I think. I don't know what to do with the, since I can't find my 'Paint.net' folder.
Hope this is the right place to post this cry of anguish. Any help would be much appreciated.
