Okay, then you might have to change the Play Store app. To do that, download "Root Explorer" from the market. And then download THIS. Then navigate to the "system/apps/" file using Root Explorer. Delete the Play Store app and replace it with the one you just downloaded. Reboot, it should work fine now. But if it still doesn't work, you might need to reconsider another rom.

Well the best thing to do currently is actually get another rom, there might be an error to the coding of the rom you used. Just make sure while installing a rom, you remember to do factory reset,wipe cache, and wipe dalvik cache. And you should be fine.

It may have problem because of wrong file permissions.Give the command chmod 644 /system/app/{Playstore filename.apk} in terminal.
For example:
chmod 644 /system/app/PhoneSky.apk
chmod 644 /system/app/Vending.apk
chmod 644 /system/app/com.android.vending.apk
or change it from an explorer like root explorer setting the permissions like that:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
**You have to make system partition rewritable in order to do this**
**If you just change the file permissions it will be better to wipe cache and dalvik-cache**
You could also download a cracked version of playstore and you see if it works better.(It has option to restore to original version if you like):
GooglePlay.Installer-4.3.11-OriginalIcon.zip

Here is a guide

Just try to remove your google account.Use titanium backup or system application manager to clear settings and data for playstore.
Then get into recovery and try to clear cache , dalvik-cache.

OK I will try this method

Try to clear settings for other google services too:
Google Play Services
Google talk
e.t.c...
Then get into recovery and wipe cache and dalvik-cache again.
