1) Close Dogecoin client 2) Going to your data folder: on win7, C:\Users[your name]\AppData\Roaming\DogeCoin 3) Delete your blk0001.dat, blkindex.dat, and /database folder (don't delete wallet.dat) 4) Restart v1.4 and resync with network
You'll have to resync the entire blockchain but it should work.
Hello xbudahx, many thanks for your advice, now it's work well.
I am using v1.2 client and have not sync to network few days, today I upgrade to v1.4.1 (windows), I exact the zip files in new directory, but when I run new client, I got those error message:
"EXCEPTION:11dbException Db::get:Not enough space C:\docments and setting\administrator\□□□□\dogecointqt-v141-win\dogecoin-qt.exe in processMessage()"
Does anyone have detail infomation about CGMiner's paramter configruation, like as what's relly mean of "I" value..... The readme docment only point few infomation about these.
