I've been using Returnil VS 2008 v18.104.22.16802 quite happily on XP. I've recently had to move to a backup copy of XP on another partition (old one was getting bloated and having problems) and now I get the error "error message: df error 2002:2, Failure to control the service:The system cannot find the specified file." when I try and activate Returnil. I checked the eventlog and found this in there: "The description for Event ID ( 1838 ) in Source ( RVSystem ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event:" I downloaded v22.214.171.12483 but I notice that no longer offers the option of memory caching, just disk caching which I don't want, so I'd be grateful if someone could help me get the older version working again.
