Cupti buttons sticking after dropping

[Bouncepounce89]

KANGERTECH CUPTI buttons are jammed after I let it fall on the floor. When battery is removed I can press the buttons and they feel great. But as soon as I put the battery back inside the sticking of all 3 buttons happens. I reallY love this mod and I don't want to part with it. Has this happend to anyone before? If so, PLEASE help me . Any advice is welcome.

Same problem only it's only the 'ignition' button sticking and not really giving a positive 'click' on mine. Was googling a replacement part and ready to get soldering iron out but looks like I'm going to have to bin the thing now. Driving me mad. Anyone fixed this?? It's an expensive and otherwise quite a good mod.
