You need to go into the phone using Tiki and pull out the .jar and .jad files to this program, delete the folder, update the database, reinstall the JAR and JAD files, then re-update the database. Search for the thread on application instllation in this forum, it'll tell you everything you need to know to install apps to your phone.
Nothing that requires data will work if you just download it from the website over the air. You need to install the program via Tiki for it to work right. Good luck.
