I guess I need to put app install instructions:
1) Make sure you have ROM manager. The free one works, the Pro gives added functionality.
2) make sure you set up ROM manager properly
Go into ROM manager, click the button on the top that says "flash clockwordmod"3) install the app.
Tell it your device, making sure you select the one that ends in mtd
Tell it you've flashed manually
Tell it 3.XX
4) use the app.
There is a bug report button for a reason. I will not help you if you have an app issue and there is no bug report attached.
If you have a fascinate, there is a fix posted in the thread, but it is an issue with either your ROM, or a past kernel you installed. It moved your apps data to a place that is not standard to CM7, therefore the app does not find the zip.
