Importing blogroll – only get part/half of it

I’m importing an OPML file from Blogrolling–no errors. The problem is, only about half of it is getting imported into the database.

Is there a limited number of links allowed in the wp_links table? (Maybe ~200?) This particular blogroll has around 300 (yeah, I know) links in it, all of which are to be imported into one category that describes the blogroll. I do have another category set up for another blogroll, and that one’s got around 50 in it–it imported with no problem at all.

Knowing how some people have gargantuan blogrolls, I can’t believe nobody’s tried importing them into their WP databases until now; all I can ASSume is that the problem is its size.

If that is the problem, how do I increase the size of the table in phpMyAdmin? (Sorry, I’m a SQL-tard on my own.)
