Normally if you always use Start_Wallet to launch your wallet it should update automatically.
But if for any reason it doesnt do the following;
1.close wallet
2.backup wallet.dat
3. delete everything
4. download new wallet
5. start wallet using Start_Wallet
6. you dont need to wait till its finish sync, just close it again once it has started the GUI
7. put back wallet.dat
8. start wallet using Start_Wallet
9. Go to tools, wallet repair and choose "Delete local blockchain folder"
10. wait till its done syncing
11. if you still dont see any coins, Go to tools, wallet repair and choose "Rescan blockchain files" and then "Rebuild Index"

This did the trick for me. My block index was stuck but got everything moving and syncing again after complete reinstall. As nokati said, MAKE SURE YOU MAKE A BACKUP!
For the impatient ones among you (like me), who like a virtual countdown: testnet v2 was launched on April 13th. Testnet v3 on July 8th. Testnet v4 or Mainnet on October 5th?
