Sorry for the confusion, what I meant was that sometime yesterday Eon removed the 277944 patch from their site and replaced it with 277171. Now today they removed 277171 and replaced it with 277859. Currently, the only patch available from Eon is 277859 (but this might change by the time I finish typing this :o). According to Dale's post earlier in this thread "277859" "broke a few things", and the next two (277929 & 277944) made things worse. So, if this is the case (and I have no reason to doubt Dale's comments), the latest "stable" patch would be either 277171 or 277255. Since I don't use Render Cow, I have no personal knowledge whether or not 277859 will cause problems with Render Cow or not (some indicate that it does in another thread). Again, the Patches that "were" made available are: 276828 277171 277255 277859 277929 277944 Though this might be too late for some that are having problems rolling back to an "older" patch, one thing I always do before applying a new patch is to make a backup of my entire "application" folder from within the Vue program, and if problems arise, I simply restore the backup of my application folder. The entire "application" folder is slightly under 50 Mb. Re-installing the "older" patch seems to work for me, but some here have commented that there are possibly certain files that do not get restored when you do a rollback to an older patch. Restoring the back up of the "Application" folder would make certain that "all" application files are rolled back.
