First, a bit of history of the major changes I made:
1. Last night I added a sprite that was 256x256 and it seemed to work fine, I didn't have any errors with it.
2. Last night I added various special functions that just worked with variables and some sprite switching
3. This morning I worked with some more special functions involving variables
4. I added a 96x96 sprite and it seemed to work fine.
5. Made some special functions on my collision layer map involving the 96x96 sprite
6. Created a new map in the project and worked in the collision layer in the map
7. Tried to add a sprite with initial instance to the new map
About the time of #7 is when I started having all the problems. When I start up the project, I get the following errors: "Error loading map: Path not found" and then I get "Run-time error '91': Object variable or With block variable not set" and then the program exits. I was able to get into the project earlier and I would try to load some of the tilesets while others I wasn't able to load or even reload. The first problem I remember having was when making a sprite, I had some problem with a template, got the runtime error '91' and then this all started happening. I've looked over my current project .gdp and a backup in wordpad and the map files look pretty close except for where I've added variables and tilesets and can't figure out where I went wrong. I'm using version 1.4.5 (and that's the version I'm required to use unfortunately).
