Hi Billy,
There certainly was an issue as the forum login was supposed to be syncing with the main site (forum and front page are essentially two different applications), but it was broke, which caused problems for Tapatalk. We turned that bit off until we can apply a fix, meaning that Tapatalk should be ok. At least I haven't seen any complaints since (till now <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="

" title="Smile" /><!-- s:) -->).
Can you describe what happens? Does it simply not log you in, or does it give a message of any sort?
