language file 7.0.0 vs 7.1.1

Just installed 7.1.1 and exported langiage so lang_en.php was created. as i wanted update my language file translation i originally created for 7.0.0 but I see 7.1.1 lang_en is quite different than was for 7.0.0 . Strings are in different order etc... I have no chance to actually compare it now with old file. What to do ...I dont want to make again ahole translation if I done that already for 7.0.0 an idea what to do ?  thx in advance..

hmm Am lost ..  I really cant figure oiut how to update translation. Guys there must be alot of people here who updated translations ... how u actually found added and/or changed strings if strings are totally in different lines in new version ? Its impossible to actually maniually or visually compare it - it would me easier start from scratch than try find every string one by one if itzs same or changed or new one... hope somebody can help me here ..

This community is not like the phpbb community where you can resolve all problems without fees. Here, they seem to only offer their services if we fork out some money.

Like the code for the 7.09 license I paid for was screwed up and they blame on my server, since I install the 7.1 version on the same server and it's running fine.
