An error appears when translating: exceeding the usage limit

not work

when creating www pages, it is spontaneously inserted into the web code, simple translate code. So I have to turn it off and on again.

just says error: service usage limit reached when I first tried to use it. fucking trash

Sometimes work, sometimes not, I don't like when something is not reliable, it's just frustrating. When you translate any language to English work best, when it comes to other languages and inter-translation between them don't work so good, sometimes grammar is so bad, and that is a shame, specially because this guy want money on a monthly level for this, only an idiot can pay him that.
