Installed v2.0.1 over 2.0.0 - caveat

[alexf]

Great work Tim! (sorry I couldn't work on this beta - too busy now that I got a paying job).

The download and install instructions in the download thread say to copy the \Data folder to other place when upgrading from 2.0 and then to overwrite this one back. You should point out to copy the \DEM folder too (if used). Too easy for people used to 0.9 and deleting the whole folder and losing the DEM files (guilty :-[)
