On your Exchange server, in \exchsrvr\exchweb\6.5.7653.21\ there should be a folder called "Controls-Originals copied by Enterprise Vault". You can copy the files in this folder back to your \controls folder in the same directory.
I'm not sure that proxycfg is the faulting part here.
This is how EV gets the Version string (this is where he get the "6.0" for /exchweb/enterprise vault/<version>):
var version = "";
var verUrl = g_sBase + ((g_sBase.charAt(g_sBase.length - 1) == "/") ? "" : "/") + "?cmd=EVSettings";
var oHTTP = new ActiveXObject("MSXML2.xmlhttp");
oHTTP.open("GET", verUrl, false);
if(oHTTP.status == 200) version = oHTTP.getResponseHeader("EVVersion");
I think the command returns the wrong Version number...
I suggest that you log a case with Symantec for this...
