1.9, 32bit - Program hangs on exporting texture

[Ferase]

Hello.

I want to start by thanking you for making this program, it was a real help in ripping models to rig. I have an issue though: upon selecting a texture, hitting the "Plugins" button, and selecting either "Export to .png" or "Export to .tga," the program hangs entirely. The "Edit" plugin functions flawlessly, but the texture output buttons do not.

Here is the information about my project:

• The Unity ".asset" files were extracted from an iOS app
• The Unity version the game runs is "U4.5.4f1"
• Models have extracted flawlessly with version 1.8b of your software, but the plugin dialogue hangs the same as texture exportation in 1.9 (versions 1-1.8.1 function properly for me, but I cannot export the textures since they were never supported until now. I know they are supported because the ".png" export dialogue came up once in 1.9, but never again following; just crashing upon hitting "OK.")
• I'm running Windows 8.1, 32bit

Any help would be appreciated. Thank you!
