I wrote about this problem here for two reasons.
1) C2 was/is the only program (so far) that has this problem.
2) I was thinking that someone here might have encountered a similar problem and perhaps had help to give
Thanks! I first created two new users (one with admin rights and one without). I tried reinstalling C2 with both users, but the same error showed up.
I have also installed the latest version of nw.js, just to make sure.
Anyway, so this morning I succumbed and upgraded to (free) Windows 10. I updated the drivers for my graphics card.
However, the problem still exists, but now the error message is slightly different again, but still something unsearchable like "Can´t find entry point in (/¦.dll"
Thank you!! I tried Beta 226 now and it seems to work. I haven´t bought anything from the store lately, so my problem may have other origins. I would however very much like to know what dll I might be missing, or what else causes this problem.
