i think you should leave the wallet open for a while and check that peers connect to your wallet
atleast one peer should connect with your wallet to update the blocks
if prob not solved then
make a text file in your wallet folder andcopey paste this command in textfile
gdbix.exe attach
rename text file node.dat and then open it gdbix command promt will open then find some active node copy and paste them in the command promt your nodes will be updated and your wallet will start downloading blocks
i hope it helps
