boost_cache table not being created

I've had boost working for a while and after updating to the last dev version I realized that boost wasn't working, then I saw that the table boost_cache was broken (I was able to see that it was there, but couldn't edit or see contents). Then I disabled boost, uninstall, re-enabled and got the following error. Since then I tried removing and adding again the module, also tried with the 6.1.18 version with no luck. Somehow the boost_cache table doesn't get created, and then boost is just a fountain of errors.

I think that perhaps if I rebuild the boost_cache table manually the problem may be fixed, but I don't know the columns or characteristics and I am not good enough to read them from the error, if someone can read them from there or want a submit a dummy boost_cache table for me to copy the table I'll be happy to report any success.

Thanks in advance and this is the error:
