hello keeprlit welcome to the forum!!!
sorry to read about this,...its just so unfair sometimes especially to the spouses of the british nationals..they keep on changing the rules and it involves loads of money ,anything to discourage people coming into the UK from outside the EU.

''On 26 July, we announced that English language tests will be compulsory for these migrants from 29 November 2010.
From that date, any migrant who wants to enter or remain in the UK as the partner of a British citizen or a person settled here will need to show that they can speak and understand English, by taking an English language test with one of our approved test providers. The term 'partner' means husband, wife, civil partner, unmarried partner, same-sex partner, fiance(e) or proposed civil partner.
The tests will be compulsory for people applying from within the UK, and for visa applicants from overseas.




....since you and your wife got married jan 2010,its covered and she needs to take and pass the English test and this should go with her spouse visa application ,..the solution that i can advise is to take the english test here in the UK and apply for spouse visa again.
