While downloading/installing the new update, pressing the exit button or ending its process, the temp starmade-starter file you were downloading will not be removed.
The next time you try to update, it seems to conflict with that and refuse to update entirely and give you something like this: {F7115}
Only option is to stop updating again and this will then finally replace your starmade-starter.exe with the temp file you started downloading.
Making the file corrupt.
Uploaded a v15 starmade-starter.exe to test with: {F7114}
