Invalid Payment token--client machines will not process cards
Things were working fine and suddenly this problem yesterday
Only main server can process credit cards-- every other work station comes up Payment token invalid.
Have tried signing in and out of merchant account on server and restart. Signed in and out of other client computers as well and restart and still cannot process. A big problem for a retail store. On phone with our support last night--no solution. no one is sure what to do. We are stuck ..any help please??
