Yeah, It frustrates me even knew about the proprietary *.hir format for IR files on the line6 site that only work with line6 stuff, but doofus me forgot. I was looking for an Eminence Legend IR and websearch turned up a link to a Choptones essentials IR on both the choptones site and the line6 site. It was a tad cheaper on Line6 site (6.79 vs. 7.99 on choptones site) and for some reason I just shrugged and said, well it's a bit cheaper, and I won't have to create a new account at choptones. I totally forgot that there was a difference in IR formats on the line6 site vs. normal IR wav files.
Upset with myself and kicking myself, but lesson learned.
