If you can only import your friends partly, that probably is normal, more about it can be found here (missing friends).

If the import does not work at all or you think it misses to many friends, you can only do following:

• be aware that the html file you saved contains personal data (a list of your friends)
• accept and be ok that I can see that data if you send it to me
• send me a mail with your html file

Be aware that I will only use the file to test it and check if I’m able to improve my import logic and will delete the file afterwards. If that’s ok for you go ahead and send me your exported file.
