Earlier today, I downloaded a screencorder. My antivirus said it was corrupted, so I fully uninstalled it (with Control Panel). Next, I installed the dev kit to toy around with it and see if it was my level of coding. I tried running DD, and it said something was preventing it from starting. I fully uninstalled the dev kit (from control panel again). Yet again, I had another error...launching. When I clicked the shortcut it didn't run at all, and running it from Win32 said i was missing steam_api.dll. I installed that from the internet and it seemed to work. Well...it didn't. I tried playing it, and the loading screen came on. I waited 30 seconds and nothing happened, so I clicked it on the taskbar. Two things happened. First, a really weird window showed up. It had the sword, Dungeon Defenders, and the closing/minimizing icons, but a huge bar of that stuff below it. When I tried to close it, a window showed up saying that DunDefGame isn't responding. I might try a reinstall, but I don't want 130 hrs of work to be erased. Other than that, I don't know what else to do, so I have come here and hope that you guys can help me fix this; I just wanna play my game ;D
*IMPORTANT*: Up until now, this game has been working perfectly and I am very satisfied with it. I am using windows 8.1 (or whatever the latest is). I purchased the EV dlc on Friday. This is the screencorder http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CCkQFjAA&url=http%3A%2F%2Fmatchware-screencorder.en.softonic.com%2F&ei=kaR6U-bwI-qrsASb9oHgBw&usg=AFQjCNG7VWoXZD8BPIxT-LP1lrF5jjGUMA&sig2=rXRn8my_MzjpTpM-yPWUGg&bvm=bv.67229260,d.cWc.
This is the steam_api.dll http://www.dll-files.com/dllindex/dll-files.shtml?steam_api
EDIT: Also, I restarted after every uninstall
Another edit (I forgot a lot): I have a COMPLETE SteamApps backup, if that can prevent me from losing my stuff
