rousemark: "Now where is that darn "Get eBay fees" button?"
Rousemark, the eBay fees button can be found under the TOOLS menu. Click on eBay Fees Manager. A new window will open up. Go to the eBay Fees menu in the new window and click on Retreive eBay Fees. Select the dates that you would like the fees to be imported and click OK. If you would like the fees to be applied to your spreadsheet, go back to the eBay Fees menu and click Apply Fees To Main Database. This should solve your problem.
Most of the functions that people are used to having individual buttons for are now under the Tools menu. If you can't find a button for something, look there.
I hope that this helps!
