why did i get an error in the app that i am from russia and adobe is no longer working.

The country associated with your adobe id must match the store you purchase from and must match the payment address. otherwise, change what's necessary:

change country associated with adobe id - https://helpx.adobe.com/x-productkb/policy-pricing/change-country-associated-with-adobe-id.html

change credit card and/or billing address, https://helpx.adobe.com/manage-account/using/update-billing-information.html

change currency - https://forums.adobe.com/thread/1999694

change store - http://www.adobe.com/store_selector/storeselector.html

change adobe.com website language - https://forums.adobe.com/thread/1999693

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Account, Payment, & Plan forum so that proper help can be offered.

Is your account registered as Russia?

Did you purchase using a Russian credit card?
