Try the troubleshooting in this article starting from Step 1.I have an invalid profile error message.Sometimes this is not possible and the player will need to delete their old save and make a new save so they can continue playing the game, in these cases our support agents can return the inventory (Cars, Credits, Vanity items, Wheel Spins) we can identify from your last save You don't need to use these from your game itself but Steam needs them to display inventory correctly.This article is meant to provide troubleshooting to attempt to recover an older or lost save for players.

If you have a participating trusted server then you can use a privileged Steam API key on the server and grant explicit items for appropriate situations. These APIs are called using an internal "Client API Key" that is assumed to be untrusted. Steam servers manage the playtime and drop frequency per-player. At appropriate times, the game client invokes ISteamInventory::TriggerItemDrop. Rather you select certain items that can be dropped, and configure a drop frequency. However because the client can't be trusted (and the keys in a client can always be captured by an attacker) you can't give users specific items in this scheme. Users can also purchase items directly from the Item Store, or trade and exchange markets in the Steam community. Without a game server, the game client can communicate directly to the steam service to retrieve users inventory contents, consume and exchange items, and receive new items granted as an effect of playtime. DescriptionThe Inventory Service can be used in two ways - either server-less or with the addition of a trusted server that knows game state. Please leave us feedback or ask questions in the Steam Inventory Discussions in the Steamworks Developer group. The Steam Inventory Service is a set of features that allow a game to enable persistent player inventories without having to run special servers to manage users or items.
