Cannot download Multiterm 2021 SR1 after uninstalling Multiterm 2021 SR 2

I had to uninstall both Service Release 2 (SR2) for Trados Studio 2021 and MultiTerm 2021 because they just prevented me to continue my work with a project. I have downloaded Trados Studio 2021 SR1 again, but cannot download Multiterm 2021 SR1 again. Since I paid for these programs, I would like to know why I cannot revert to the previous version. The new version just does not work for me.
