Overcoming interaction with H specifier while staying on subfig package

Question

I know that from the float package and subfig you get a bad interaction with an H specifier. (see: Numbers keep continuing - Problem with subfig and ContinuedFloat)

I tried to just add subcaption package to correct this problem, however i get an error saying:

LaTeX Error: No counter 'subfigure@save' defined .

Now the problem is that my thesis has been already written, and only one figure that runs over 3 pages needs numbering correction due to this issue (it starts with 3.14 and ends with 3.12 as you flip pages, however it needs everywhere to say 3.12). Throughout my thesis all my remaining subfigures are correctly numbered. Unfortunately, it is too much work and I do not have enough time to replace all my subfigs to subcaptions package.

Now two questions:

• is there a way to make these two packages work (subfig and subcaption)?

If not...

• Is there a way to force this figure that continues over 3 pages (while using subfig package) to have the same figure number in each page?

Thanks a lot in advance.
