The wallet software should be updated on both pc's. The old wallet software will not connect to the network. Make sure you have a backup of your wallet.dat file, and or a backup of your private keys somewhere before any updates.
The old wallet has just been fired up yesterday after sitting in a closet turned off for almost 4 years, it syas out of sync on the wallet and the transactions. I did back it up, I also tried letting it recreate the BC folder except the wallet.dat but that just moved my coin to unconfirmed and still no connection. I moved the files back and no issue there. I tried to add some old nodes I found but that didn't help any. I tried to send my coin to the new wallet but that didnt work either its just sitting in the send. Not sure what to do from here?
That old wallet won't work anymore. You need to download the new wallet. Make sure and backup your Wallet.dat copy it to another location. There is functionality in the wallet that will list you as a bad peer and not allow you on the network with the old wallet. The new wallet has a bootstrap and update button it is Automatic!
