L!M!T, i had the same problem as shafted, but with v.9bu-2. havent had a chance to test out 1.0. the problem occurred with many different combinations of ISOs. from 2 small iso up to about 7 or 8. happened when using the rename feature and without. tried a lot of different ways, but it just seemed to not want to run at all. the error comes back immediately. the single iso function works fine, but batch mode refused to run at all.
i had sent you a bug report a couple weeks ago via email. it had a screenshot included as well. once i get my xbox back onto the network i'll try again. got a bunch more ISOs to copy so looking forward to testing out the new version
