after system reboot after a unexpected power outage I recieve the error message "I/O error 1392" with OK button. Clicking OK message window disappears, no PA window visible.
Task Manager shows PortableApps.com (32bit) and child task PortableApps.com Menu task in the task list.
PortableApps is not accessible.
Steps taken so far.
Closed all tasks and start again - same error
disconnected USB-drive, reconnected and start - same error
system rebooted - same error
downloaded PA platform installer 22.0.1 and repaired existing installation - same error
System Windows 8.1 64bit
any idea, error message not listed on support site, no results in search
