Without looking at the loan documents it is difficult to evaluate your options. Do you mean the "winter quarter" that has passed? So were you promissed money for the loan but then did not receive it?
You should do a lot of what you are already doing. Review your loan documents, contact people, and find out what the blocks are to the release of your loan. Once you know the blocks, then resolve them, and document everything (notes of calls, copies of letters and emails, etc.).
