in a proper install there shouldn't be any mysql errors, http://city.nwg-nv.ru/mta is a site that i found that uses 2.0 and works fine. mine is installed using the update from beta to 2.0 and works fine.
it is still possible that you have errors, i code on this every now and then when i get a chance, and not alot of testing goes into it before a release. if it works on my server, then i release it. originally i didn't plan on releasing anything to the public, but i will still try to give support when needed.
