Help with ve config remote

Im trying to change setting in a mulitplus II.
I have downladed thr file via vrm and opened in ve config.
The file from vrm is a .rvsc.txt file.
I tried to load a file that save via file-save, which i see is not the correct way.
If I modify the original file save by using “X” will cerbo / multiplus reconize the .rvsc.txt file?
The warning i got from cerbo yesterday said it needs to be an rvsc file.
I have read the instructions below, it says it supposed to be an rvsc file from vrm.

It should not be a .txt file.

It should be labelled… Xxxxx.yoursiteid..xxx.rvsc (or .rvms)

Do you have full control on the GX through the VRM?

Ok, just tried again on my laptop and now its a rsvc file.
I originally downloaded on my smartphone and it adds. Txt to the end.
Was able to change settings successfully.
Thank you.
