Marco, the reason why NoOfRows() doesn't work in this case is the one we suggested all along. Your tables are being autoconcatenated. And you can find out yourself in the above script log. Look at the message between code lines 0144 and 0149. It says "due linee recuperate" but there is only one line in InstagramSites.
That means that QV decides to autoconcatenate the data from InstagramSites to the previous table with an identical layout: TwitterSites. That's why QV tells you it did a load of 2 lines.
To prove my point, have a look at the document in attachment. It contains the script code from approx. SentimentAPIs until after InstagramSites, LET-statements and all. When you run this script, the Table Viewer shows only 2 tables while there should be three. If you Preview the TwitterSites table (rightclick) you will discover that the row from InstagramSites resides in this table.
As Rob suggested, add NOCONCATENATE before the InstagramSites LOAD-statement and you will be fine. Check the remainder of your script for other spots where this problem might occur. Better too many NOCONCATENATEs than too few.

BTW you can add long log files as a text attachment to your post. Use the Advanced Editor to get the option.
