First, V6 might be awesome but it is totally useless to me as I am constantly tweaking most of my logos and I'm not going to recreate them in V6 at this point. As a bit of background info, I've had the same problem V5 when I bought that version as was mentioned in another thread, it won't take my unlock key but still works and I never got an answer on that. I have no idea if this might have something to do with my problem. Now, to my problem. After installing V6 and discovering that I couldn't edit the previous logos in it I just went back to using V5. At first, I went to open some of my previous logos and found that they wouldn't open any more. Some would and I just worked from the version that would open. (I may have several versions of one logo, different arrangements/sizes, etc.) Now I am finding that I can't open ANY version of a particular logo for some reason. Now I have absolutely no access to a logo that I need to edit. To be more specific about what is happening, I click on the TLC file to open it, it opens the window like it's going to load the logo but nothing happens. No error message, nothing. It just doesn't load. I don't know if it has anything to do with installing V6 and that interfering or not. I'm not savvy with the whole programming thing and have no idea how it works. I just know that I have spent an enormous amount of time creating quite a lot of logos and now I can't use them. Could V6 be affecting V5? Or could there be some issue with V5 because of the unlock key not working properly? And if it is a problem with V5, how can I resolve that? Thanks for any help you can give me. I've tried several other logo creation programs and I have enjoyed TLC more than others.
