I installed TMAdict 2.0 on my n70 (on a 128M memory card) but I can not remove it. Then I remove the 128M memory card and now I'm using a 512M memory card and I want to install TMAdict again but I also can not. Please help me!!!

Just get into the system root ( C and E) to delete all the file relating to TMA Dicts
Actually, for such kind of Dict, we do not need to install, just copy and paste. That's all
