I'm very happily using Traffic Grapher 6.2.2... I downloaded and have tried using PRTG NM8 with quite a bit of frustration. I have read the words about "importing" but the hooks just don't seem to be there - it's sure not evident. I really don't understand the relationship between the two and would rather just sitck with TG 6.2.2 ... BUT .. I feel I should try out the newer software. The newer software seems to continually pop up web pages when I'm really trying to use the Windows GUI - so what's with that??!!
