Opening packages in 2021.

Hi,

I'm quite new to Studio, and installed 2021 two days ago after working with 2019 for about a month.

A client has sent me a package, but I saw that instead of having the Studio package icon next to it, as before, I suddenly see a MemoQ icon (I use MemoQ as well), and when I clicked on the package MemoQ opened instead of Studio.

I've also noticed that all the previous packages I've worked on now also have the MemoQ icon next to them. When I tried to open the package using the "Open Project" button, as I had previously done, I wasn't able to find any package, as the system was  looking for files with an .sdlproj extension, whereas the packages I have end with .sdlppx.
