I now did the following

Stop both miners
Started the bitcoind.exe in the deamon folder. (for good measure, I also added it to the trusted-files-list of Comodo)
It showed an empty console-screen (I had to copy the .dll from the bitcoin.exe-folder to the deamon folder for it to work)
Started both miners again
After a few minutes, still no result other than the aforementioned

Does bitcoind.exe have parameters which I should use?
Can I give other information which might help? I am not using any flags btw.

Oh, I actually meant "bitcoin.exe -server" instead of bitcoind, my bad. Don't know if it makes any difference, though.
