Hello, SkylandBeast.

Thank you for contacting our Microsoft Community Forum. Please accept our warmest greetings and sincerely hope all is well.

We understand that you can't play Roblox anymore after downloading it previously from the Microsoft Store.

The message "GET THIS APP WHILE SIGNED IN TO YOUR MICROSOFT ACCOUNT" does not actually mean that a Microsoft account was associated to your Roblox account. It only means a Microsoft account was used to download and install the game but not play it.

Since you forgot your account or password for the game you need to contact Roblox that actually developer of the game for help on this issue. Microsoft can only help you with downloading and installing with game but with everything else it has to be Roblox that you contact. Please use the links below to get the help that you need.

Thanks again for choosing Microsoft! We’re here when you need us.

To confirm, you have an Xbox app installed on your Windows PC?

Try to check this link https://www.xbox.com/games/store/roblox/bq1tn1t.... Sign in your account and click on GET or Install to.

Thanks, but when I try to get the app from the Microsoft Store it opens the Xbox app, and I already tried signing out and signing back in.

download roblox from the microsoft store, log in and then it should transfer to your roblox account then you can log back into your normal roblox app or site.
