Text Tool won't work

My text tool is "stuck" on horzontal text tool in PSE10, and any attempt to change results in program crash.  I cannot even "reset" all tools without triggering the fatal crash (it's telling me that "ATMLIB.dll" is not a valid Windows file).

I've got Win 7 and more then enough resources to run the software. Actually it ran just fine until recently.  Is ATMLIB possibly pointing to a font issue?

I've reloaded the software from scratch (that is I've de-installed, and re-installed it now a couple of times).  I've reloaded it and used the regirstration code from Adobe's "my products."

It only seems to happen when trying to select the text tool.

Any ideas?  (I did post another message pointing to the DLL but I'm now more suspecious that it might be a font or registration issue.)

I've wasted days trying to resolve this, any help would be appreciated.

thanks.
