Bad @DATA instance format

[hamidialii1990]

When I open the arff file, I get this error:
This line is in the last line in my arff file.

Bad @DaTa instance format in line 3096: free.fr,False,http://www.free.fr/adsl,2.0,5611,719,420.5199999999132,754.3740000000653,3627.99799

Could you please upload either the full arff file or the arff header so we can reproduce this issue?
