PyxelEdit has a grey window at launch

in Bug reports
Hello!
I have a problem with PyxelEdit, in my windows8, it's work, but I want to work on my Windows7 and on this computer,
when I launch PyxelEdit, I have a grey window, like a previous post in the forum. I downloaded the latest adobe air version and
delete the PyxelEdit folder in AppData, retry to install or launch portable version: nothing change
For the history, I try the latest free version on this computer, maybe this version can corrompted my complete version?
Thanks for your help! (and sorry for my language, I'm a french student!)

I can't use software with this problem... (screen: http://uplmg.com/_yx)
Thanks!
So, the problem is a another problem
I retry to search why my version does'nt work!
Sorry for the delayed response!
That's very strange, deleting the settings usually fixes this issue. Have you tried any other Air apps, to see it it's an issue with Adobe Air? For example one of these sample apps: http://www.adobe.com/devnet/air/samples_javascript.html
Thanks for your reply!
Yeah other Air app works on my computer : for example (http://uplmg.com/em2, http://uplmg.com/rrn, http://uplmg.com/4-v)
I have no idea why PyxelEdit doesn't work..
I tried to reinstall both versions, delete settings or install another Air version..
It's done, thanks!
