In some cases users have reported this problem after an application or system crash, leading the RF Explorer for Windows application unable to work from that point on.

The root cause is likely a truncated or damaged configuration settings file, probably the outcome of a prior system crash. To make sure all those old files are deleted and we start fresh from default settings, please follow the next steps, they are a bit different for Windows XP than for Windows Vista/7/8/10, so select the right steps for your operating system.

Important: this process will delete the RF Explorer for Windows application preferences (such as color mode) and will reset everything to default. However, this will not delete the configuration frequencies you may have stored by name (Named Settings) so these will remain untouched.

For Windows Vista/7/8/10:

* Close RF Explorer for Windows and any other application.
* Open a command line started "As Administrator"
* Type the following command:

    rd "%localappdata%\RF_Explorer"   /s   /q

* That will delete all obsolete files. To make sure no settings remain, the next command should return "file not found" or equivalent message:

    dir "%localappdata%\RF_Explorer"  /s   /b

After these steps are completed, please start RF Explorer for Windows (no need to reinstall, just run it normally) and contact us if the problem persist.

For Windows XP:

* Close RF Explorer for Windows and any other application.
* Open a command line
* Type the following command:

    rd "C:\Documents and Settings\%username%\Local Settings\Application Data\RF_Explorer"   /s   /q

* That will delete all obsolete files. To make sure no settings remain, the next command should return "file not found" or equivalent message:

    dir "C:\Documents and Settings\%username%\Local Settings\Application Data\RF_Explorer"  /s   /q

After these steps are completed, please start RF Explorer for Windows (no need to reinstall, just run it normally) and contact us if the problem persist.
