Flash CS4 Crashing on Import to Stage

I'm trying to import a psd file into Flash CS4. I can get as far as designating how I want layers to import, but once I hit 'import,' Flash crashes. This has happened 6 times now, and I don't know what to do - I've rebooted, I've done what I know to do. It was all working fine last week. This has just started today.
I'm using Adobe Creative Suite 4 Design Premium

Here are my computer specs:
Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB

Boot ROM Version: MBP41.00C1.B03
SMC Version (system): 1.27f2

Sudden Motion Sensor:
State: Enabled

Any ideas on what's happening here?
