I would stick to 7.57 / 7.58 as these are stable versions and cover vehicles up to Oct / Nov 2014. Don't forget that you may also need the S1279 add-on module. This is the additional module that goes inline between the VCI and the diagnostic port to be able to communicate with some passenger vehicles and most of the commercials with any Fiat / Ford influence. You can always try without it and if it will read all the ECUs then great, if not, you may need the add-on.

Pop up your VIN, just so I can see what version of Relay you have - there are stacks of combos of these. It's also important to make sure you have a full chip Lexia kit of you have a later van with CAN mutliplexing. Sometimes a connection issue can be becasue of the cheaper kit, or may be an installation or communication issue.

Ok, so yours is a 2012 Jumper III (badged Relay III in the UK), so will likely need the module to properly read some of the ECUs.
