Chough, I want make sure you understand I'm not an expert on this gadget but I am glad to help you to try and make this work. I uninstalled TCPMP player and found another download site for the TCPMP altered version at this site.

The first link is the Cab installer. I downloaded that and installed the cab file on my MicroSD card. I then double tapped the cab file and installed it on the SD card in a folder that I labeled Storage card/Program files. It installed fine into a folder labeled "TCPMP". Then I navigated to this folder and double tapped the execute "player.exe". It takes about 20-30 seconds to come up on the first run, but after that it loads fairly quick and plays a good variety of files (mp4, avi, wmv, etc.). So if you want, try download this again and give it a try. I hope that it works for you.
