There's a store that has recently shut down with some great, cheap deformers, so now that I don't have access to them I'd like to copy them from one of my accounts to another.

I've downloaded [account A]'s deformer, while using [account B], in the form of an xml and tried using mesh helper to turn it into a dae, which it did. I then uploaded the dae and set the levels of details to 0's, but when I wear the object... nothing happens.

I'm not sure what I'm doing wrong.

@hwarren101 i dont know what you try to copy, if its clothing, animals, then you can use mesh helper 
if you copy a building then mesh helper don't work on that becourse mesh helper is for making something rigged
when its a mesh buidling/object then copy as dae file 
or maybe the xml file is to big then you must use the xml splitter

I made a thread with info and tool if its needed,

@Lagertha
I'm aware of those usecases, but deformers are a little different. As far as I know, they're mesh that mess with your rigging a bit to literally deform your avatar beyond the means of the shape editor. That being said, I'm not sure why the rigging is being lost when using mesh helper.

@hwarren101 don't reply please for answer someone use the @ i change it for you 

but why still meshhelper? there is a good new working tool, 
try it maybe it don't give that problem,
if it gives a problem then you can ask it in that thread, on the creator from that tool

Deformers are just how the mesh is rigged.They'll adjust the skeleton to be smaller,larger,crunched,etc.They need to be exported and imported as a rigged object,not as a normal object.

@Lagertha right.

anyway @Necrok , that's what meshhelper does, but for whatever reason it doesn't seem to work when i uploaded the dae i compiled using the xml. idk what im doing wrong.

Are you going into the rigging tab while uploading and marking all 3 boxes?If not,the skeleton will be normal SL one,without joint positions or scale.
