I know that I was not the only one before who could not submit to the library...and I still the only one? The tech support people told me it was "fixed" but I just found a way to sneak into the upload section and I find that my .zipped file that I added NINE DAYS AGO is only "1k." This means that the upload system was NOT fixed as they said. I have emailed them in the interim, and still have received no response. If you too have submitted something and not heard from them in a while OR if you are unable to submit like me, please sound off so Stardock will fix the problem.
My experience with Stardock has been not the most positive since purchasing the game. I am hopeful that we can work to getting this resolved.
My experience with submission and editing my mods and deleting one has worked very well. I would suggest that you try uploading from another computer, perhaps a Internet cafe, or a friends computer. PC's are troubling frustraiting things sometimes. When no one is looking I sometimes use a pencil and paper.
