Hi all I'm now ready to put my base map on my ecu I got a base map emailed from omex but can't seen to get it from my email every time I try to open it it says it can't find the software to open file , am I doing something wrong or is there a way of copying it without opening it it's a c20 let turbo map

Have you downloaded the software from the omex website ?

yes map 3000

There's a later download now so you may need that one..

Which one will I need

Just downloaded map 4000 the problem I have is I don't know how to get the map from email to the map 4000

During the install of the omex software, it would have created a directory for maps. You need to save your emailed file into this location. If you don't know where it is, try opening the software, then doing a 'save as' and note the location.
