Please help me and it is quite urgent.
Started from last week, I could not use the Mist and Ethereum wallet on a window environment. I always uses the test-net, however, it just stop sync again. I have removed and reinstalled it. I tried the latest version. It stopped to sync once the initiation of the Application was finished (once the full testnet downloaded). Sometimes, it just re-downloaded everything again. Thank you for your help.
