Hi, please read my post
http://www.panoramio.com/forum/viewtopic.php?t=33961 where i was in the same situation. To correct those PO Errors, OPEN THE .PO FILE WITH PSPAD (the program does have LINE NUMBERS-you can see exactly where is the Error).
But first, please read my post, where i explained some examples of errors in PoEditor Message Error Windows....after that, if you have trouble, send me the PO FIle, and i will correct the empty spaces (lines) for you...
