Hello @lomikins and welcome to our wonderful community. I am sorry to hear that happened to you. You should be able to re-install the game with no problem and as long as you have been playing the game either thru Facebook or King.com, once you reconnect it to either one of those you should get back to your most recent level and have your gold bars restored. Unfortunately you will have lost any saved boosters and saved lives. These are stored locally on the device you are playing on and once you delete the game - that memory is cleared so you will need to start over again as far as saving boosters and/or lives are concerned.
it would be awesome if the game designers could let the users store the file that keeps track of the boosters in another location so that if the app is uninstalled or switched to a new device, the file with the boosters can be transferred over.
