This is strange - Stand Alone won't open psd files

Another thing that worked recently, but doesn't anymore!

Since several filters suddenly stopped working as PS CS5 plugins (yes, I have a thread on that already), I tried using them via the stand alone method. I would swear up and down that I was able to open a psd file via the stand alone last week.

Now I get this error message from FF:
Unknown bitmap storage format in file 'file location & name here'(0 was expected).

So, this was pain. I changed the file to a jpg and it worked ok.

I also tried opening as a dng. That opens, but through processing turned a 2848x4288px file into a 256x170px file.

What on earth has happened?

I'm on a Mac OS10.6.5 and I have updated both PS and FF to the most recent versions.

Thanks, Totte.

I am also encountering an apparent file size limitation for jpgs. Does anyone know what this is before I try a dozen iterations?

Better yet, how can I get back the version of FF where everything worked from PS?

Thanks. I think my FF just got corrupted because I have the Pro version.
