i don't have Delete everything out of c:\users\<username>\AppData\Roaming\StabilitySharesXSI (keep wallet.dat in there and stabilitysharesxsi.conf if you have one)
at all
?!? what now?
Are you saying you don't have anything or that you deleted everything but the wallet.dat?
After you delete the files make sure you shut the wallet program down completely by going into task manager and ending the task.
You can get to task manager by pressing CTRL+ALT+DELETE and choosing it or by right clicking the taskbar and choosing task manager. Make sure its fully closed then make sure the files are gone (except wallet.dat) and then restart the program.
You are on windows right?
