SK1 - There was a bug in CrackMem that refused to delete Vendor.xml from the Apploader folder if there was a previously removed copy of the file in the RemovedFiles folder. The fix in v2.6 was to delete the copy in RemovedFiles. Now, it works correctly.
Just wanted to mention... I just checked in Windows 7 64bit version and I found the vendor file in C:\Program Files(x86)\Common Files\Research In Motion\AppLoader
