If your wallet won't even start, i think it's a problem on your computer. Try to download it again.

Anyway, something is moving! Today my wallet received a new block. Don't know why, but now it seems stucked at block 116678 (+1 from what it has been for weeks). I still see a lot of orphan blocks received.

Can someone please explain how could i switch to one of others chain fork? Should i delete all my downloaded blockchain and try to start downloading it again???

I need suggestions.

Thanks
