Using ASAM Software with IMPLAN data

I am using ASAM, which is an excel based open source software (http://www.webpages.uidaho.edu/commecondev/asam.html) unaffiliated with IMPLAN. I need it to perform gross. vs. base contribution analysis. Has anyone used ASAM? I have run into technical difficulties retrieving the implant data automatically for one of the counties in my region. I did not have this problem with the other counties. When I try to “Retrieve the implant data automatically” (checking the first box), and import the IMPLAN impdb file for the Duval county model I have built in IMPLAN, here is the message I get: Run-time error ‘3205’: Too many crosstab column headers (347). What does it mean? Is there a way to debug the code? Is the only way to overcome this problem to manually create ASAM? Manually creating ASAM has been tedious, and I have seen no good results yet. Jimmy, can you respond?
