haha. no. grammar for some of the latin-based languages is ridiculously hard to master. you have trouble with the grammar even as a native speaker. It's not the grammar.
What's the difficulty? The pluperfect is one of the easier tenses in French. Its formation has no exceptions--one of the very rare tenses in French with no exceptions: imperfect + past participle.
And its usage directly parallels the pluperfect in English:
I had finished my meal when he arrived.
J'avais fini mon repas quand il est arrivé.
