logic express crashes on startup
I'm running Logic Express 9.1.7 on Mac OS X 10.6.8, 2 GHz Intel Duo Core, 2 GB 667 MHz DDR2 SDRAM. Whenever I click its icon to start it up, it begins to load, checks the plugins, then all of a sudden the screeen flashes as if it's taking a screenshot, and crashes -- just quits, too fast to read any error message dialog box. I removed all plugins expecting there to be a bad plugin, That didn't solve the issue. Besides, all my plugins work with other DAW software.
Any help you can give would be appreciated. I'm using Reaper right now because I need a working DAW, but I'd prefer to be back on Logic Express. Vesides, I need to access past projects.
