Photoshop keeps showing 'strtable error' when opening PSD files?

Question

I'm on a near new late 2013 model MBP/OS 10.9.4 running CC2014.
Anybody encounter this and figure out whether it's a Mac OS or an Adobe issue... or even better, what it is & how to fix it? A quick search hints that it might be related to the wrong file extension being used, but these files are all standard PSDs with the correct file extension. Several have been created recently using the new-to-me CC2014 PS app I'm using to open them, so at first sight CS->CC version compatibility issues seem unlikely.
So far I've still been able to open the PSDs by ignoring and clicking through the warnings, but it obviously doesn't promote a relaxed frame of mind ;-)

Answer 1

Thanks for the suggestions Arpit - they helped me find and fix the issue.
Results as per below. I suspected the problem might be text/font related hence the additional steps.
- Created new file
- Quit PS
- opened file > OK
- Added editable text to file
- Quit PS
- Opened file: strtable error
- Restart machine
- Opened file: strtable error
- Reset PS preferences
- Opened file: strtable error
- Opened in plugin disabled mode
- Opened file > OK
- Deleted FontExplorer plugin
- Opened file > OK
- Quit PS
- Reinstalled FontExplorer plugin
- Opened test file & others with editable text > OK
So, in the end the problem was with the FontExplorer plugin and replacing that fixed it.
Thanks again for the help.
