App stops working after adding messageUI.framework - xcode

Question

App stops working after adding messageUI.framework
I have a fully working App created and I want to add some new features. I added the messageUI.framework and it stoped working. If I delete the Framework it works again, but this is not the idea.
The error I received is:
-[Account initWithCoder:]: unrecognized selector sent to instance 0x1cd953a0
I have a custom NSObject called Account and I get the error when loading it:
myAccounts = [[NSMutableArray alloc] init];
myAccounts = [NSKeyedUnarchiver unarchiveObjectWithFile:savePath]; //Crashes in this line
When it was previously saved with:
[NSKeyedArchiver archiveRootObject:myAccounts toFile:savePath];
Can it be caused by some overlapping variables or something like that?
Notes:
Account.h is like:
#define kAccName #"name"
#define kAccID #"identifier"
#define kAccInitAmount #"initAmount"
#define kAccActive #"active"
#import <Foundation/Foundation.h>
#import "Transfer.h"
#interface Account : NSObject
#property (nonatomic, strong) NSString *name;
#property (nonatomic, strong) NSString *identifier;
#property (nonatomic) double initAmount;
#property (nonatomic) BOOL active;
- (id)initWithID:(NSString *)ident;
#end
And Account.m is:
#import "Account.h"
#implementation Account
#synthesize name;
#synthesize identifier;
#synthesize initAmount;
#synthesize active;
- (id)init {
self = [super init];
if (self) {
self.active = TRUE;
}
return self;
}
- (id)initWithID:(NSString *)ident {
self = [super init];
if (self) {
self.active = TRUE;
self.identifier = ident;
}
return self;
}
- (id)initWithCoder:(NSCoder *)decoder {
if (self = [super init]) {
self.name = [decoder decodeObjectForKey:kAccName];
self.identifier = [decoder decodeObjectForKey:kAccID];
self.initAmount = [decoder decodeDoubleForKey:kAccInitAmount];
self.active = [decoder decodeBoolForKey:kAccActive];
}
return self;
}
- (void)encodeWithCoder:(NSCoder *)encoder {
[encoder encodeObject:self.name forKey:kAccName];
[encoder encodeObject:self.identifier forKey:kAccID];
[encoder encodeDouble:self.initAmount forKey:kAccInitAmount];
[encoder encodeBool:self.active forKey:kAccActive];
}
#end

I just hit this problem, I cannot tell you exactly why, but refactor your Account object to any other name, I used Accounts, and it works. Something at runtime in the MessageUI.framework is colliding with your Account object name.
