Is it possible to file a lawsuit against a gaming company for loss of accounts that were stolen, due to neglect.

This is a video game which many spent substantial amounts of money, buying items. The co. that owned the license for the game, revoked the license and acquired the accts from the co. running the game. During the transfer of accts., many were stolen, due to neglectful coding. They also refused to recover these accts. This co. has an office in the US and we have the names of those responsible for the defect.
