For those with corrupt wallet.dat
1) create a folder named protoalt and keep it's path in mind
2)Copy all the files except your wallet.dat into the new folder
3) Create a .bat to start the alternate you have created
3)start your client with -salvagewallet, this does exactly that.
4) once your wallet is recovered, start the alternate client, it will create a new wallet for you.
5) send coins to new wallet and use it as main one now.
Note: it's advisable to keep a copy of all your wallet.dat files in secure seperate storage in case of data corruption. For those with Client start issues
Try starting your client with -reindex in console. this will reindex the blocks on your hdd and then connect to the network to sync.
Mac os /Applications/ProtoShares-Qt-0.2.0.app/Contents/MacOS/ProtoShares-Qt -reindex
Windows -- /yourpath/protoshares-qt.exe -reindex No Block source
