The .dll has a version number -- there were 4 versions of 1.2.4, please check the properties of the dll to see which it is; e.q. 22.214.171.124
regardless of that, I ran successfully on 126.96.36.199 & v188.8.131.52 -- so something else is going on.
I need to have you (using the beta 184.108.40.206 please ) run the program in debug, step through to the listMergeVarAdd.FormatInput() function and find which
statement it's puking out on.
Line 75 is the create of the XmlRpcStruct in the beta, but it appears to be getting an exception on trying to add one of the options -- so I'm thinking that the stack trace above was from the 1.2.4.x version.
... and just for the hell of it, if you want to get passed this on a temp. basis, try running this command as serial/json instead of xml-rpc
