Cant get any files to read on arduino

I am brand new the world of proffie and I got through all stages of getting everything set up to upload to my board… except now i cant get a single thing to actually read I keep getting no such file or directory. At this point I just want to put the old config files back and give up but I cant even get those back on. Can anyone please help me figuring out where im going wrong

Yes, we can help you.
However, without seeing the exact error message, it’s hard to know what is wrong. Use the “copy error message” button in arduino and paste it in a reply to this post. We may also need you to post your config file so that we can see what’s in it.
