    Why does the payment screen for the creative cloud change from english to portuguese?
    I'm trying to sign up for the photography creative cloud with lightroom 5 and photoshop. When I click on the "buy" button is takes me to the payment page, but my country changes from the U.S. to Argentina and the language changes also.
    I've tried contacting Adobe, but they're ways of contacting them are a pain in the ***. The chat doesn't work and I'm on hold forever when I call.

  • Why does my lock screen glow green?

    Why does my lock screen glow green? It does it quite often, no affects on  the phone.

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

    Chances are you are looking at the place holder of a large image. Go to the preferences and check that View Large Images is checked.

  • Why does my Imac screen slide and I lose my screen?  It goes back to my desktop.  Then sometimes my screen goes to full screen and I don't know how to get out of it.

    Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
    Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over. 

    Hi,
    When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
    On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

  • Why does my Mac screen suddenly go dark? Sometimes it stays dark for an indefinite period after waking up from sleep.

    Why does my Mac screen suddenly go dark? Sometimes it stays dark for an indefinite period after waking up from sleep. I have to open and shut the monitor screen to get it to light up again.

    Might try posting in the MacBook Pro laptop forum. This is the Mac Pro desktop forum.

  • Why is the login screen Red?

    My login screen (where you select your profile and enter your password screen when you first turn the computer on) is now red all the time.
    I can't remember what image it was before, but it's for sure not a Red screen. Everything still function, but just not sure why it's Red.
    I recently used Time Machine to restore a backup, does that have anything to do with it?
    This is what i mean. And I don't know how to flip this image around!

    Hey brianblue,
    With the latest version of iTunes, the dock icon for that application is now red. See this article for reference -

  • Why does new 5s screen look like the old 4?

    We just bought and backed up two new 5s replacing iphone 4. Why does one new 5s screen look like the old 4 iphone. One phone shows new version, one is still old. I have downloaded and backed up twice, same thing happens. Used icloud to backup.

    Sure, here's two photos, LP5 is the old screen style, NP5 is the correct screen. Note the differences?

  • Why does my mac screen suddenly get big?

    Why does my screen suddenly zoom in? I can't figure out what triggers it and how to get back to normal display size

    Thanks Yellowbox. I wasn't using a track pad, but the solution was the same for my mouse. Somewhere along the road I missed the fact that a double click on the mouse zooms and unzooms.

  • Why is my login screen pretty slow?

    About a days ago, my login screen would come up immediately whenever I opened my laptop . But now, it takes about a couple of
    seconds and I have to sorta tap my enter key or any key to make sure it doesnt go back to its 2nd cover picture. 
    I've provided a link to what im talking about

    ImKervin,
    Along the same lines of what was suggested above, you may also want to consider performing a
    clean boot. 
    This could allow you to figure out what is causing your delay by process of elimination.
    In addition to the above, try to
    reduce the number of unnecessary files or
    software sitting on your hard drive.  A decrease in performance is noticeable the closer your drive gets to capacity. 
    Optimizing your hard drive is another way you can improve your computer’s performance. 
    While it is set by default to run weekly, it couldn’t hurt to check its status.
    Hope this helps!

  • Why does my phone screen flash red an not work??

    why does my phone not work an keep flashing red??

    Is the computer closing down and restarting whilst left unattended ?
    Is the computer running other tasks in the background eg downloading, security upgrades/scans, or disk indexing ?
    Have a look at

    * and note suggestion to use session restore feature to prevent this

  • Why does my passcode screen not display correctly, since ios7

    I STILL hate ios7 -- doesn't make me dizzy, but sure does hurt my eyes.  I find it MUCH hard to read the screens.  Here's an example of what I sure think is a BUG, with this new display design -- my passcode screen is SUPPOSED to look like the one on the left (and it occasionally/rarely does), but it USUALLY looks like the one on the right.  Keypresses are not in any way indicated -- you can't really tell what number you're hitting, and you can't see if you've accidentally hit it more than once, or how many you've entered.
    Am I the only one experiencing this?

    Okay, I figured out from other posts that, if I change from my background to an Apple-provided background, I don't have this problem.
    So the next question is -- WHAT is required of a custom background (due to the overload of whiteness/brightness in ios7, it's REALLY important to me to have my background be all black, to provide the contrast I need to see things) for it to really work, in ios7?  Why doesn't the all black background that I used, with no problem, in ios6, work anymore?

  • Why does my macbook make a funny noise when I open it?

    After my macbook pro has been on the charger for some time & I open it up, it will make a funny noise & the screen will be blue with a bar on it.  Takes a little bit before I can use it,  Does anyone know what is wrong?

    I quit all applications & close the lid.  I usually use the charger all time.  If I leave it unplugged from the charger, it will not do this.  It will make a whirring noise & the screen will be blue over my background, will have a bar on it like it is loading.  Then will finally let me use the curser after a few seconds.  Only had the macbook for about 4 months.  It started doing this about 2 month after I bought it.
    If you are still under warranty and/or have AppleCare, call them.  Let them deal w/it.
