1.7.4 TGB Pro "Error reading PNG file: incorrect data check

I was creating imagemaps and animations for a game that I was prototyping when my cpu spiked and I started getting some slowdown. I saved my project and shut TGB down and took a break. I cleaned up my memory and some other stuff on my laptop, then I started TGB back up and recieved a message prompt that read: Error reading PNG file: incorrect data check. The title of the prompt read: Fatal-ISV: (..\..\source\dgl\bitmapPng.cc @ 85). The screen displays a distorted image of last saved project. When I hit the "ok" button TGB shuts itself down. Here's the specs of the system I using: OS Name: Microsoft Windows XP Professional, OS Version: 5.1.2600, Service Pack 2.0, Processor: Intel(R) Pentium(R) M processor 1.80GHz, Memory 1014MB, Video Adapter: Intel(R) 82852/82855 GM/GME Graphics Controller. My rig is so beastly everybody should get one of these monsters!!! j/k... Any help would be great because I done 2 uninstalls and 2 reinstalls and I gets no love from TGB.
