Please download the latest installer from
www.stockalyze.com and run it. You don't need to uninstall Stockalyze.
But, before you do that you will need to cleanup a little bit:
1. Make sure Stockalyze is not running.
2. Go to "%localappdata%\Lunetek\Stockalyze\data" and delete the only .lyzdb file present there.
3. Go to "%appdata%\Lunetek\Stockalyze\yahoo_data_download\yahoo_index" and delete all files.
For steps 2 and 3 just type the address in Run window and click OK. Please see the attached image.
Sorry for these details but to solve it quickly this was the only option.
Please let me know if you face any problem.
Thanks,
Sacha
