P.S - I have also installed new copies on new windows 7 machines, none of them load.
Is their a new wallet out?
working fine

Hmm i have 4 separate computers which should be staking. 2 different internet connections. None of them load. The wallet has crashed a number of times. If i turn my PC off half the time the block chain becomes corrupt.
Not exactly what i would call fine.
Keep in mind i have 2 separate internet connections and now 4 different PCs. All brand new. None of them work. Every other wallet i have works. Something is not right.
No problems here either, my wallet hasn't missed a beat!!
I am running 3 different TRON wallets on 3 different computers all on the same network, and they have been working fine. all are staking very nicely. Not sure what the difference would be.
2 laptops, one desktop, and using a cisco router. all working fine, have had no issues.
Try deleting all your info in the %appdata% files except your wallet.dat, and reload one at a time.
