I just checked his website (at least the one I know about):
Index of /chdk/Works well for me. Lists:
http://malbe.nm.ru/chdk/allbest-ixus65_sd630-100a-50.zipDownloaded and opened the ZIP file--seems OK.
One issue you may have--many ISP's (and probably corporate networks) block sites in the .ru (Russia) domain. You may need to try a proxy and see if you have better success...
I will post the SD630 ZIP file here for a day (then erase--I think that is OK here) so you can download it from here.
Good Luck,
