Welcome (officially) to MobileRead and glad you were able to solve your problem.
Now we have one more problem area and solution to check if something happens to our reader.
I have learned that I should only load 1 pdf at a time to keep the problems minimal and make it easy to back out when a loading problem occurs. Also, I found that larger pdfs always cause my reader to load forever and sometimes freeze halfway through the book. So, now I try to avaoid pdfs as much as possible
