Thanks for the quick reply Matt, much appreciated. Not sure which causes it, I tried restoring both a number of times then gave up after the crashes. Since MC26 was installed on the same machine as MC24, it inherited its library and so things were fixable (I changed the settings manually to what they used to be, took a minute or so), but yeah, odd. After fixing everything I backed up the library from MC26, then upon installing it on a second box (the HTPC) I was able to import everything fine. So...restore MC24 settings and library to fresh MC26 install causes crashes, but MC26 to MC26 doesn't. Odd. I can send both library files for you to have a look, just need to know how.
MC26 also seems to have a host of stability issues, after getting used to the smooth action on 24 these hangups and crashes are a bit jarring but I am sure they will be fixed in not time, like always.
Thanks again,
Doru
