One more update: i found the guy with the same problem, Site Admin said him to put "English.ini" file in the lang folder. I found the translations for Bandicut, copied the text from the
https://www.bandicam.com/bandicut-video ... nglish.ini , created the ini file, and it's still not working. But, now Bandicut is not even giving me the error, it's just opens and closes automatically (check it in task manager).
Installed new copy of the Bandicut, it had 5 more files than the old copy. Now new copy of Bandicut allows me to select the video i want to cut, but when i choose one - it crashes. At least I can open it again
