Question Problems with HP/TQ in Evoscan

First, I'm a newbie using Evoscan. Second, I did search other posts and did find a couple of posts by Mfred on the issue but nothing pinpoint specific to my problem. I'm sure I can't be the only one with this problem and am also not sure if others have found a solution yet.
The problem: After logging a 3rd or 4th gear pull in Evoscan, I go to calculate the hp and tq but it says my max hp and tq was achieved @ 0 rpm. Also, the dyno plot is way off. Instead of the hp/tq following the rpm, it is displayed way to the right and is incomplete. If anyone knows how to capture the screenshot of the graph, let me know and I'll post it later when I leave work. I did read something about repositioning where rpm or speed is logged with repsect to time in the folder with the code. I haven't tried that yet because this issue I'm having seems more like a settings problem but I could be wrong. I am going to use DLL later to see how it relates to Evoscan and my actual dyno numbers. I understand that the hp/tq calculations in the logging programs are only approximations but although time scaling was off, the numbers from evoscan were within + or - 10 whp/tq of what I saw on a dynojet fwiw. That was surprising.

My primary use for Evoscan is to log knock activity from various gas stations in my area. I have always had my suspicions but just needed to confirm the good gas from the bad. The hp/tq thing would just be a + if it worked correctly.
Thanks in advance. Answers, explanations, comments, tips, and criticism, are all very welcome.

i'm pretty sure it's a known bug, and that he's working on it. so sit tight, he'll get to it or you can use DLL, or mrfred's spreadsheet.

Thanks. Did Mfred post a link to his spreadsheet? I wasn't aware that he did. Thanks for the info.
