surprisingly my icloud control panel 1.0.1 is working perfectly for me.
yesterday i installed fresh windows 8.1 pro and did the following:
THIS STEP IS TO MAKE SURE U GET AS MANY PICS AS POSSIBLE:
installed control panel 1.0.1 and let it download pics, it will download about 100 pics, when it stops,signout, delete the folder mediastream, sign back in and change the download folder to a new folder, again start the photostream(this time manually ), when it ends it will download some new pics as compare to first try, signout again, uninstall the version 1 and install version 2.1.2, do the same it will download more pics, now uninstall this version and install the newst version, and it will again download the remaining pics. now copy all the pics in one folder and overwrite/skip the same pics. doing this it you will probably get all the pics. now to make sure ur future pics downloads instantly u will need to uninstall version 3 and go back to version 1 and let it setup itself it might start photostreamdownload process again, let it do it and dont worry about anything.
so hopfully after doing this the new pics taken by us will instantly be added to photostream without any delay.
this is how i managed to fix my problem.and its working 100% perfectly.
if ur not worry about ur old pics then leave all the installation of all 3 versions, just install version 1.0.1 it will download 100-125 pics and will stop, but from this moment you will start receving pics normally.
i hope this works.
