Can't upgrade towers

Published on Wednesday, November 6, 2019 By dannyboy1701 In Siege of Centauri

Played the game with no problems when it first came out.. now when I go into campaign or any modes I can't upgrade any of my towers.. Have uninstalled, reinstalled, updated, I verified the integrity of the game files.. still have the same problem... game plays fine just with no tower upgrades.. any help would be nice..
