Descriptive Problem Summary: Every time i try to open up my dreamseeker with a game, a error comes up that says some kind of instruction referenced memory could not be "written"/"read"

Numbered Steps to Reproduce Problem:
1)Go onto programs and uninstall BYOND
2)Go to http://www.byond.com
3)Click Download BYOND
4)Install
5)Open up a game
Code Snippet (if applicable) to Reproduce Problem:? The instruction at "0x77fcb0c8" referenced memory at "0xff3f3891". The memory could not be "written". Click on OK to terminate the program


Expected Results: I expect this error to stop coming up

Actual Results: The error still comes up

Does the problem occur:
Every time? Or how often? Every time sometimes twice before the program ends, sometimes once and it ends
In other games? I can play some games, however i cannot play games like DBZ:Heroes United and Final Fantasy V Another World, and in each different game that has an error a different error comes up, same words, but different numbers in quotes
In other user accounts? Yes
On other computers? No

When does the problem NOT occur? It always occurs

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.) It did not occur in version 470, but that was before i took a break from BYOND now that im back to BYOND it happens for every version, and i have tested, i played BYOND on this same computer with the same operating system

Workarounds:
I've tried to delete the whole BYOND folder, and install EVERYTHING else, but once i put it in the recycling bin, i could not move it out
