problem replying to threads

[cmack91]

everytime i go to a thread THAT I POSTED, it automatically signs me out, so i cant reply. i can read it but not reply. this doesnt happen on anyone elses threads that i look at. only on ones that i started. before this started happening, i would click on the arrow to the left of the title to see my replies, and it would only show my original post, and if i clicked the arrow next to the "last posters" name, the page would freak out and keep trying to reload over and over again so that i couldnt do anything at all, not even read more than one word at a time before the whol page turned white and it loaded again. im wondering why that is, any sugestions? does anyone else experience this? and since i cant reply to your posts please PM me and hopefully that will work
