Currently only Debian can upgrading 32 into 64 bit. Ubuntu unfortunately cannot. The only way is to clean install (64bit). If you have a lot of data, better backing up before do that. If not, shouldn't be a problem.
Should you have /home partition separate from the installation, retain the /home in advance mode. Still, better to backup though.

Natty 11.04 offer at installation to reinstall system files while keeping user files (but doing a backup remains a goo idea...).
Simply boot on a Natty 64bits CD, and in first screen, choose "Upgrade system". The 32bits system files will be replaced by 64bits system files.

Can you help with this problem?
