Apps not working?

[MysticThunder]

again Im back with more strange questions.

Was downloading programs for my phone off of "OMARKET!" and "Windows Marketplace"

all three said they were installed- but when i open them through the phone, they all give me an error message that says:

ERROR

an unexpected error has occurred in [app name].exe
Select quit and then restart this program, or select Details for more information.

Details just gives me a bunch of incomplete script text. I've tried restarting, they repeat the error. I've reset the phone, still no luck. Not sure whats wrong- I've never had them default install incorrectly.

Anyone help?
