What could happen?

Haw to restore contacts that i had before .... ??

You should probably contact Plaxo Customer Support. Have you checked your deleted items? You can also check on Plaxo Online - note that there may be more than one contacts folder on Plaxo Online, so it's possible that your contacts are in a different folder.
