im currently using nokia 7610. however i cannot get the games started. they just disappear after i put it into my phone? why is this so?

Could be a hundred reasons. Some of them:

1. Not enough memory, press and hold the menu key and it'll show you what tasks are running.. close everything except 'Telephone'. Select the app and press 'C' to close.

2. You're not installing the right games suited for your handset. You need s60 games, not s60v3. The games in the Symbian 9.1 forums will probably not work on your phone.

3. Your o/s is corrupt, and you need to format / hard reset.

By the way, you're kinda lost on this forum, aren't you? You posted this in the wrong section.
