It's actually not hard to recreate the .vmx file. You simply need to extract the lines from the latest vmware.log file and format it appropriately, i.e. remove preceding spaces, and enclose the values in double quotes.
The required lines start at "--- CONFIGURATION /Users/...", and end with the next section "DICT --- ...". I created a small DOS batch script which I use. This will not work on a MAC, but I will attach it anyway.
