Was the name of the File(s) Vegeta/Ssjvegeta or Raditz?
If it was Raditz you need to rename it to vegeta/ssjvegeta then put them in the right folder
I just went to check it out for you, you need to rename the Raditz and the ssjraditz files to Vegeta and ssjvegeta then put them into the Vegeta folder and the ssjvegeta file into the ssjvegeta folder then your all set
