Hi, i am totally stuck and my brain hurts

WeightWatchers-115-1-0
Taster talent potions_Normal-294-1-1
Junk Dismantling-85-0-2
Intro logo removal-150-1-3
Icons for the new items of patch 2_0 mod-226-1-0
HDR hotfix -331-v1-3-5
AA and visual enhancer-331-v1-3
Above are the copies of a few of the files I am trying to rename. I want to swap all the characters up to the first "-" with the characters after it e.g
WeightWatchers-115-1-0 ---> 115-1-0-WeightWatchers
Taster talent potions_Normal-294-1-1 ---> 294-1-1-Taster talent potions_Normal
Junk Dismantling-85-0-2 ---> 85-0-2-Junk Dismantling
I tried using the below expression, but they rename incorrectly.
RegEx(1)
Match: (.*)(-)(.*)
Replace: \1-\3
I will continue reading but i am hoping for someone to help prod me in the right direction.
Thanks
Tiller

This is what you need:
1. Set RegEx (1) as:
MATCH: (.*?)-(.*)
REPLACE: \2 - \1
2. In the Remove (5) field, check "Trim" (that'll remove any spaces left at the beginning of the file name).
3. Use the preview to see if everything's OK, and then press "Rename".
One thing; if there's no space before/after the hyphen (e.g.: "Title-Artist") it will be added as a result of the renaming process (e.g.: "Artist - Title"), which may or may not be a problem for you. If that IS a problem, then you're gonna have to use two different RegExs.

Seems to have the right way to do it, now I need to find out why it worked
