Hello, it may be that the system prohibits running password security controls; Please use ie browser; In Tools-Internet Options-Security-Custom level, ActiveX controls and plug-ins are enabled rather than disabled; Then download the password security control again and log in to the online banking. Please update the flash software; I suggest you use ie browser. If you are using IE browser, if you are using IE8.0 and 9.0, please use compatibility mode. If it still doesn't work, please completely uninstall the old online banking control, click the red prompt in the password input box to download and reinstall the new control. File deletion paths: c: \ Windows \ System32 \ drivers \ peckp.sys and C: \ Program files \ PSBC IBS security suite 2.3. Please ensure that all files specified above have been deleted before reinstalling. I hope I can help you.
