I own GalCiv Gold + Twilight of the Arnor and try to update all GalCiv versions via Impulse to the latest updates. Unfortunately, it does not work, but in spite of letting it try to download for *hours*, there comes always a "experiencing network difficulties" message. Sure my network works just fine, and I can download a 5 MB file from anywhere else in seconds...
With Stardock Central, downloads always worked fluently and without such problems, so why cannot Stardock offer these downloads via Stardock Central, if Impulse doesn'r really work?
