Check in the directory "/7.6/Logs/" if you have any error files, generated by the import process.
If there is nothing special and, as Carl said, that the csv files aren't empty, try to copy those csv files in the "/7.5/csv/" folder and try importing again.
The CSV's files are no empty. I'll try to copy all the CSV's files into the folder "7.5\ CSV\(...)" and i'm going to try again.
I found this error in the directory "/7.6/Logs/":

Which version of JRE (java) do you have on your desktop? 1.6.x?
That error appear in every file of the logs directory.
The version of java is 1.6.0
Weird. Why is it pointing to "C:\Archivos de programa\BMC Software\DataManagementClient\7.6\CSVs\Foundation\COM-Company.csv" if you installed a new data management tool?
Did you reinstall it in the same folder?
Did you change the "Data Management Tool" path when you try to import in aruser?
I uninstalled Data Management Tool and Data import and DeveloperStudio, then I installed again all the aplications on the same folder.
Ok. And so csvs are in "/7.6/csvs/" ? or in the "/7.5/csvs/" folder?
if you are receiving a "Bad Record" error, then you need to look into the spreadsheets to ensure you have completed them correctly.
Also, you can import them manually using the import tool and the mapping files found in the directories to see what it is not happy with - most likely a field format or missing data.
