Problems after updating to 2.2

[deb410s]

i just finished updating to froyo 2.2 and it went well except my downloaded ringtones are gone! Also it says "problem loading widget" on my homescreen. The time is gone and weather. How do I fix these problems. I did do a backup before upgrading. Any suggestions will be appreciated.

Ijust finished my froyo 2.2 upgrade. I now cannot change my default incoming voice ringtone. No matter which tone I select, when the phone rings it uses the "Noisy" tone. Tried to reload the update and the update button will not illuminate, therefor cannot reload the update. Do it only allow one update?
