Feature Failing to Regenerate

I'm fairly new to Creo, and I'm having some trouble. I keep getting this error message saying that the feature failed to regenerate. When I switch the view mode to unattached, it shows up how I want it to look after the extrude is finished, but when I click accept, creo tells me that there is a regeneration failure. When I hit okay, the feature I was working on disappears.

The two pictures are:
1. What the model looks like in an unattached view
2. The sketch view of the feature

Any help would be appreciated.

Your pictures are too small for me to see.
Check your part accuracy, try changing it to a smaller value and then regenerate.

I don't understand from the pictures what you're trying to model, can you explain better and with larger pictures?
