Depending on where your base folder is, try typing in C:\assets\base into the box which says base path. My base folder is in D35k709\base so i typed in this.

I'll try to pinpoint the location of the program that might cause this problem. Hope it'll work. Pakscape really is the best and easiest program for pak files etc.
Edit: Found the problem, the reason why pakscape couldn't open the files was that all the pk3 files were in a folder with japanese letters, realized that when i could open the files in the base folder without a problem. Thanks for your assistance.
