I can't export my VModel into moc3

Vampauli

Hey,
I finished my VModel a few days ago, but I coudn't export it into moc3 anymore. I already did that in an early state of the rigging process and back then everything worked. I tried older backups of the file too, but this didn't worked out as well. I'm frustrated and sad, because I did everything and now the easiest step isn't working. Help me please or I'm dying in pain. It's my first VModel and it was so much work omg-

Oh I forgot to describe the details, I'm sorry.
The Problem is, that everytime I click on Export for Runtime and as a moc3 file it starts processing and the loading bar is doing it's thing. But then when it runs through and finishes there still is no data saved in my explorer. It's like saving the whole time but when I look it up there is no moc3 data file because it didn't export it somehow
