v3dmm manager problem

[Heroheenie]

Recently I reinstalled 3dmm in order to try it out. I got it working, but I noticed that expansions I had deleted were still in the manager. So I tried deleting them through the manager, and it "failed to delete" it. Even when I reinstalled the expansion, it "failed to delete". So, what do I do?
Edit: I fixed the problem by setting it to run as administrator.

Go to the following directory:

C:\Users\ YOURUSERNAMEGOESHERE \AppData\Local\VirtualStore\Program Files (x86)\Microsoft Kids\Virtual3DMM\Expansions

In the "YOURUSERNAMEGOESHERE" part, put your windows username.

Select the filenames of the mods that you'd like to delete, and delete them.
