If the numbers don't look right, check the file positions.txt first. If you have an unexpected end position, either you have an off-setting start position or there's a split on the stock.
Scan the P/L report to see if there're trades missing for entire months. If so, open the html file in your browser to see if it's valid. If not, rerun IBpnl download. Otherwise your account activity has resulted in a file format which IBpnl cannot handle. If you email us the statements in a zip file, we'd be happy to change IBpnl for you.
If you report a problem, please give us your email address and describe the problem in as much detail as possible. The error message is the most important piece of information.
