I just went through this myself,
Your old wallet won't sync because there was recently a hard fork and they need to be moved to the new chain.
*wallet.dat can be found somewhere along the lines of C:\Users\UserName\AppData\Roaming\Einsteinium if your using windows*
1. Make a copy of your wallet.dat file from the old wallet(this holds your balance)****DO NOT OVERWRITE IT*****
2. Download the new wallet from the website
3. Replace the wallet.dat from the new install with the wallet.dat that has your coins.
cheers,
Guy
good info there...
Einstineium has been around a long time so they have had plenty of time to make a significant agreement/partnership that can benefit everyone. I seriously doubt they would pull a Monero coin stunt.
