memory access error and .pr_xml

Hi,

1) lately while using the HTML Table viewer i keep gettig memory access error, The memory allocated to PLP is pretty good but i dont understand where this is coming from. Is it from the internet explorer?

2) Also i am wndering how can i open a protocol with extension .pr_xml. Its from Discovery Studio i learned but i am not able to open it in PLP "Open Protocol".

Thanks.
