Preset refuses to export, no error message (solved)

[Eviny]

(Sorry if I posted this in the wrong place)

So, my problem is the following: Yesterday I used my whole day to make a preset. It shows up in the preset maker, no problem, but when I'm trying to export it nothing happens. Literally, nothing. I click the button but it acts as if I hadn't even glanced at it.
 I have tried to look through the help section, but to my sight nothing like this showed up, only error message help. But like I described, with me there is no error message, no loading, no nothing.

I'd appreciate it if someone could help me out a bit with this and maybe even tell what I did wrong if that is the reason.
 I did have to edit the material file in the preset folder in notepad because of the mane, but to my knowledge that is all I did.

Help is highly appreciated from anyone with even the slighest clue of what could make it work.

Ooh, that's a tough one. Perhaps try restarting your computer? It is more than likely a browser glitch, but other than that I'm not sure what to tell you. Best of luck

Thank you for the idea. I tried it, but sadly it didn't help this time.
  Could it by any chance be the fact I had to edit the file yesterday, or could it be something else? I take any ideas and try them with open arms now to see if I can get it to work.
 
 So, game and computer restarting has been tried. Neither one worked.

Something wrong with Preset Maker, reinstall FeralHeart. Delete the folder before installing.
Make a backup with the files you need (presets, fhp, items, emotes, etc.)

Oh, thank you so much! The advice you gave me worked. Will keep this in mind for possible future problems.

Problem seems to be solved, thank you again.

No problem.
