I've had a look at your attached batch file and found an error. When I opened it in notepad, it looks normal but when I opened it in a hex editor to se the file content, there is a corruption in the Firefox line. I then reconstructed the file from scratch on my machine using notepad just using the Firefox line (as I don't have PlatinumHideIP) and Firefox fired up normally. I have then added the PlatinumHideIP line after and attach the modified file for you to try. Let me know how it goes..
