Red, I just saw the 4 VickerOilSlick files at your download site but your instructions to get them to work doesn't work.

"Download all 4 files, put all them into a same empty folder, then click on the .exe file, wich will rebuld all 4 parts into the big original .zip file." They download as vickersoislick.zip.exe, .zip0002, .zip0003 and .zip0004
I took the .zip out of their names but they're still not working.
What are the file extension ids you rename the files to so they work properly? ?
