posts don’t have tags after xml import

After exporting XML from a wordpress.com blog and importing into www.remarpro.com standalone blog, none of the posts have tags anymore. The tags exist, and the posts exist, but they aren’t correlated at all. I had lots of issues with the import, I had to break down the XML into 46 individual files and import individually, reloading the page whenever it timed out. Regardless, it took several hours and I don’t want to go through it again, it was pretty disappointing to see that all of the posts have lost their tags. Could this be a bug with the www.remarpro.com import?

Thanks!
