The error looks like you are trying to select LM2 as the module to load and it's trying to load the LM2 coding index which isn't compatible with an LM.
There's been no changes between V45 to V46 for the E60 chassis. It's the same coding data. I checked my V45 E50 data and it has the coding files for coding index .C0E (which is 0EH) the file is LM_E60.C0E
Make sure you are selecting LM and not LM2, they are different modules and have different coding indexes, LM has 0B, 0C, 0D, 0E and LM2 has 32, 33, 34, 35.
