For all those who are having loading/synching issues, I hope that you have researched the forums and found a solution. If you have tried the following solution and are still having problems, then not sure what else can be done until the application code is fixed.
I am running Bytecoin Wallet 1.1.4 on a Windows 8.1 Pro box, Intel i7 3820 3.60/3.8, 16 gb ram, and 64 bit. It took 3 times to go through the following steps until the wallet fully loaded, and since then I have had no problems. I had not opened the wallet for a few days until this evening. It went from 1300185 to 1303659 in about 11 minutes. The original load of the blockchain took about 10 hours. Yes, 10 hours. But it's not like you can't do anything else while it's downloading. Be patient. The "DB" folder is approx 26.5 gb, so it will take some time.
These are the steps:
1) First close the wallet application if it is open.
2) Find the bytecoin folder on your box. It should be located on your primary drive such as:
C:\Users\Jason\AppData\Roaming\bytecoin\.
AppData is a hidden folder, so you will have to view hidden items.
3) Go into the bytecoin folder and either delete or move the following out of the folder:
DB (folder)
blockindexes (file)
blocks (file)
Warning: Do not delete or move any other files.
4) Restart the bytecoin wallet. The application will recreate the folder and 2 files.
5) The wallet will start loading the blockchain. Give it enough time. If it gets stuck and fails to complete, redo the above steps. Remember it took me 3 times.
Good Luck!
