WBO2 Calculation Spreadsheet

Hey folks,
Anybody know where I may find a spreadsheet to calculate fuel trim with a WB? I've been chasing my tail trying to get the VE tables right using the spreadsheet Mark Mansur made up many moons ago. I finally discovered that it is shifting the rows up one row, for example dropping the 2800 RPM row into the 2400 RPM row. dave w over on gearheadefi made up one but their site over there is McF#cked. I finally got through last night and downloaded his spreadsheet and unzipped the file but the spreadsheet wouldn't completely load. It loaded about 80% then froze up. Trimalyzer is for BLM's and I've already been through the painful experience of trying to trim using BLM data. It can be done with about $100 worth of gas and datalogging many trips into town and back. Right now my only option is to sit here with a calculator and calculate every cell manually. If I were smarter I'd build my own simple spreadsheet just for idle and open throttle VE tables but, well, my avatar pretty much explains my computer skills.
