My friend sent me a document via Email and I wanted to confirm that I got it. Then I had doubt between writing to him "I've got it" (simple past) or "I've gotten it" (past participle). What is the difference between these two options in this context?
Normally, in irregular verbs, one of the differences between simple past and past participle is the using in a passive structure which requires the past participle verb for a passive voice ("For example "be gotten", rather than "be got". Also: "be broken" rather than "be broke" and so on). Even for active voice, as far as I know we don't say "I've broke it" or "I've ate it". In our case, I'm not sure if it's grammatically correct to say "I've got it" using simple past.
