Too many problems??? please help!!!!

There's too many problems with my copy!!! I just had made my first PSD and I really wanted to make my first model!!

1. When I import my PSD, the parts on the parts look missing???


2. I cannot save my file for later use!!


I've tried both 32 and 64-bit versions! No luck!!!
I've (re)installed it 5 times and I've already wasted my Christmas Day figuring it out!! And I thought the installer was corrupted???

    Other OS Description Not Available

    Thanks for your support!

    @trapflower
    System requirements for Live2D Cubism 2.1 is listed below.

    - Windows Vista/7/8.1 /10
    - Pentium4 3GHz or faster
    - 2GB memory or more (8GB recommended)
    - Storage

    Requires 5M for install and 500MB or more for temporary usage depending on length of motion tracks.

    - Internet connectivity
    - GPU: OpenGL3.3 / GeForce 8 or better
    Software may not function properly when running with an on-board GPU (e.g. Intel HD Graphics)

    There are some reports that the similar trouble to yours might been solved by updating GPU driver. Is your GPU driver the latest one?
  • No problem, @dai.s@live2d :)

    @trapflower
    If this is your laptop http://www.tesco.com/direct/dell-inspiron-n5050-laptop-intel-core-i3-4gb-500gb-156-display-black/215-3605.prd?source=others

    Then it has Intel HD Graphics 3000 GPU which is not supported as @dai.s@live2d has mentioned before...maybe you can try to update your GPU drivers.
  • I had to use it on my Surface Pro 4, I can see everything but I still can't save
  • @trapflower
    I remember I have issues with saving because I used PSD Import and manually replaced the texture with Texture Editor.
    Maybe you can try to make a new document and re-import the PSD file, then don't make any changes and try to save it. See if it works.
  • The document was made in Krita because I don't have Photoshop. Maybe that's the problem?
  • The document was made in Krita because I don't have Photoshop. Maybe that's the problem?

    Could be, make sure it's 8-bit RGB format.
    But are you using PSD Import?
    If you are importing PSD with PSD Import and want to update your PSD file, you have to go through same process. Otherwise you'll be getting error in saving.
  • @trapflower did you solve your problem while saving? 'cuz i have the same problem
    i also made a psd file by krita and my pc system specifications is fine
