SwitchRom Problem

[vigan8]

ok so after testing this great hero rom. MLIGN's Hero. i think its the best hero rom ported for mytouchs and g1s.
i did a switchrom bookmark for my cyan rom.
then i wiped ext4 and wiped phone and flashed and i kept bootlooping,
i was to lazy to try to fix it so i restored my switchrom.
everything was well until i tried to open the market and it kept closing, i tried rebooting and nandroding but didnt work. so i wiped and now its good. but the thing is, why did this happen?

Clear the market cache and make sure the cache is being stored in the internal memory.

how do i clear it?

[djunio]

menu, settings, applications, manage applications then find market on the list
