Help please from the COMMUNITY! my wallet doesn't sync!

1. Do you have version 1.3?
2. Is it Windows, OSX or Linux wallet?
1. Yes v1.3
2. windows
First of all backup wallet.dat file. (location: user/appdata/roaming/communitycoin) or export it from wallet-qt.
Then go to mentioned folder and delete everything
except wallet.dat file.
Run your wallet-qt again. Wait while blockchain downloads and syncs.
Note: appdata folder is hidden, therefore go to control panel/folder options and under View tab make changes in order to see it.
Still doesn't work. Tried with 3 PCs. Got it to work on Mac thought. Thanks for your help! Great community only here at CommunityCoin
