Time Capsule

[william7gr]

Yesterday i bought a Time Capsule. Last night i set up time machine and let my computer run over night to back up all of my files(it took like 10 hours). In the morning it was fine and did all the scheduled back ups. But then it did a back up and i got an error message saying that it couldn't complete the back up. After that when i clicked the time machine symbol in the dock it brought me to the time machine screen but there are no previous back ups, it only gives me my computer now. When i tell my computer to back up now it starts the back up process all aver again, backing up my whole hard drive even though i already did that. I can now go to all of my previous back ups in the time machine window by control clicking on time machine in the dock and selecting "browse other time machine disks" and selecting the right disk but when i do this and and click back up now it starts the whole back up process over to back up my whole hard drive.In system preferences under time machine i can't find the disk which i select by control clicking on time machine. Someone help me.
