For those not familiar, DioDict is a dictionary application available exclusively to Samsung Windows Phones.  If you've recently launched DioDict from your Samsung Focus, more than likely you received an alert saying,

"Only a trial version is available, as your device has not yet been authorized to run the full version."

If you attempt a search (using any dictionary style), you then will get the following alert,

"Lite version can be searched only up to "a". If you want to buy the full version, press the OK button."

Pressing the OK button sends you the Samsung Zone page in the Marketplace with no option to buy, download, or re-install.  This essentially disables DioDict from any practical use (unless you have an "A" word to search for).  In searching the Marketplace and Samsung Zone, the app is no longer listed.

We have yet to find any indication as to why DioDict was pulled.  We've seen apps pulled from the Marketplace before for certification issues, stability issues, questionable content and what not. This may be the first time we've seen a functional, working app pulled from the Marketplace as well as reverted to a trial version.

Which is a little disappointing because DioDict was a nice app.

Thanks goes out to Patrick for the tip!
