Programm does and cant teach you the language at all. Since its setup doesnt make it possible. With 2.000 words it is even not worth to be used as a dictionary, specialy not because of the lak of verbs.
It is even not helpfull with phrases since there are not enough. If you need phrases for your next Thailand stay, get the Audio Phrasebook Thai from Lonely Planet. At least this is a help and I am sure you will survive most situations.
The WordPower Thai is not worth its money. Can I get mine back?
